Nitrile Gloves Overview

What Are Nitrile Gloves

Professionals often look at latex and nitrile gloves to protect their hands. Nitrile gloves are made from a man-made rubber called nitrile butadiene. This material does not have natural latex proteins, so it helps stop allergies. Nitrile gloves are made to fit the hand closely. They feel comfortable and let you move your fingers easily for a long time. These gloves come in many thicknesses and colours. People use them in healthcare, labs, food work, and factories.

Nitrile gloves are strong and do not tear or get holes easily. They protect hands from many chemicals like oils, solvents, and other dangerous substances. Many workers pick nitrile gloves when they need safety and to move their hands well. These gloves do not have powder, so they help keep things clean. This is important in hospitals and when making food.

Tip: Nitrile gloves do not have latex, so they are safe for people with latex allergies.

Key Properties

Nitrile gloves have several beneficial features that distinguish them from latex and vinyl gloves. The table below shows the main features and how they compare to other gloves:

    •  Nitrile gloves are very strong and do not tear easily.

    •  They keep their hands safe from many chemicals like oils and solvents.

    •  The gloves fit well and help hands not get tired after long use.

    •  You can get them in different thicknesses for more or less protection.

    •  Nitrile gloves do not cause latex allergies.

Nitrile gloves are now the top pick for workers who need tough and safe hand protection. They last a long time and keep hands safe from chemicals, so they are great for hard jobs and careful work.

Composition and Manufacturing

Materials Used

When people look at latex vs nitrile gloves, they check what each is made of. Makers use acrylonitrile butadiene rubber (NBR) as the main part for these gloves. NBR has acrylonitrile, which makes the gloves tougher and better against oils. This also helps the gloves stop holes and scratches better than natural rubber. To make the gloves stronger and cheaper, makers add things like calcium carbonate or clay powder. They also put in special chemicals to help the gloves stay soft and bendy. These things help the gloves feel nice and fit well. The finished gloves keep hands safe from chemicals and germs. This makes them good for doctors and factory workers.

Manufacturing Steps

Making these gloves takes many steps:

      1、Workers mix NBR with other things to make a smooth base.

      2、They clean the glove moulds so nothing dirty gets in.

      3、The moulds are dried in hot ovens to get rid of water.

      4、A sticky liquid goes on the molds to help the glove form.

      5、The moulds are dipped into the NBR mix to make the glove shape.

      6、The gloves are washed to take out bad stuff and extra chemicals.

      7、The gloves are heated to make them strong and stretchy.

      8、Workers wash and pull the gloves off the moulds.

      9、Each glove is checked and packed to make sure it is safe.

Note: Every step helps make sure the gloves are safe and work well.

Quality Assurance

Makers follow strict rules to make sure the gloves are safe and work right. They use tests like ASTM D to look for leaks or holes. Other rules, like ISO -1 and EN 455, check how strong and thick the gloves are and if they stop germs. Certifications like ISO : and FDA 510(k) show the company makes good gloves and follows world rules. These steps help workers trust that the gloves will work well in hard jobs.

Glove Comparison

Nitrile Gloves vs Latex

Professionals often talk about which glove is better. They compare latex and nitrile gloves for tough jobs. Both types keep out dirt and germs, but they are different. Latex gloves are made from natural rubber. Nitrile gloves use a man-made rubber. This makes them different in how strong, bendy, and safe they are for people with allergies.

Latex gloves are very bendy and let you feel things well. Surgeons and dentists like them for their careful work. But latex gloves can rip easily. They do not protect well from strong chemicals. Some people get allergies from latex gloves because of the proteins inside.

Nitrile gloves are stronger and do not rip as fast. They keep their hands safe from oils, acids, and other chemicals. This makes them good for labs and factories. New nitrile gloves are now softer and let you feel things better. They do not have latex proteins, so they are safer for people with allergies.

A study with 356 people showed that most got allergies from latex gloves. Only a few had problems with nitrile gloves. People with latex gloves had more itching, swelling, and trouble breathing. The chart below shows how often people had allergies and symptoms:

Hospitals now use nitrile gloves more to keep workers and patients safe from allergies. These gloves last longer and protect better from chemicals. That is why many workers trust them more.

Tip: If you worry about chemicals or allergies, nitrile gloves are safer and last longer than latex gloves.

Nitrile vs Vinyl

People also look at nitrile gloves and vinyl gloves for different jobs. Vinyl gloves are made from PVC and cost less. They fit loosely and do not stretch much. This makes them easy to put on, but not comfortable for long use.

Nitrile gloves protect better from chemicals and sharp things. They fit tightly to the hand, which helps with careful work. Doctors, lab workers, and factory workers like nitrile gloves for these reasons. Vinyl gloves are cheaper but do not protect or fit as well. They are best for quick, easy jobs like making food or cleaning.

    •  Nitrile gloves are stronger, fit better, and protect from chemicals more than vinyl gloves.

    •  Vinyl gloves are cheaper but do not stretch or protect as well.

    •  Workers pick nitrile gloves for jobs that need careful handwork and long wear.

    •  Vinyl gloves are good for short, easy jobs where saving money matters most.

Doctors and factory workers now use nitrile gloves more because they are safer, more comfortable, and work better.

Types and Features

People often look at latex and nitrile gloves to pick the best one for work. Knowing about the types and features of nitrile gloves helps people choose what they need.

Grades and Uses

Nitrile gloves have two main grades. Each grade is made for different jobs. The table below shows how they are different:

Medical-grade gloves keep doctors and nurses safe from germs and fluids. Industrial-grade gloves protect workers from chemicals and sharp things. Both grades must follow strict rules to keep people safe.

Powdered and Powder-Free

Nitrile gloves can be powdered or powder-free. Each kind has its good points:

    •  Powdered gloves have cornstarch. This makes them easy to put on and take off. They help stop the gloves from sticking or tearing.

    •  Powdered gloves can leave powder on hands, clothes, or tables. This can make things dirty or unsafe.

    •  Powder-free gloves do not leave any powder behind. They help keep places clean and lower the chance of spreading germs.

    •  Powder-free gloves are better for people with allergies. They are safer for careful work.

    •  Washing hands is still important, no matter which glove you use.

A study showed that using powder-free gloves helped healthcare workers wash their hands more. This made it safer and lowered the risk of infection.

Thickness and Texture

How thick and textured a glove is changes how it works. Thicker gloves, like 6-8 mil, protect well from chemicals and sharp things. These gloves are good for hard jobs but can be less bendy. Thinner gloves, about 3-4 mil, let you move your fingers better. They are good for jobs that need careful handwork.

Texture is important too. Gloves with tiny bumps or diamond shapes grip better, even when wet or oily. Some gloves have a special inside layer. This makes them easy to wear for a long time and keeps hands cool. Gloves that stretch and fit well help stop hands from getting tired.

Picking the right thickness and texture helps keep hands safe and comfy for every job.

Environmental Impact

When people pick between latex and nitrile gloves, they also think about the environment. More gloves are used in hospitals, food places, and factories now. This makes people worry about trash and how to protect nature. Knowing how nitrile gloves affect the earth helps groups make good choices.

Biodegradability

Old nitrile gloves are made from man-made stuff like acrylonitrile and butadiene. These gloves do not break down fast. They can stay in landfills for 100 to 200 years. Newer nitrile gloves can break down in three to five years if composted the right way. First, the outside wears away. Then, tiny germs eat the rest. But you must throw them away the right way. If not, even new gloves can last a long time. Scientists do not have clear answers yet about which glove breaks down fastest.

Recycling Options

Many jobs now try to recycle nitrile gloves to make less trash. There are some easy ways to help recycling work:

    •  Check how many gloves are used to plan recycling.

    •  Work with companies that recycle nitrile gloves.

    •  Teach workers how to throw away and recycle gloves.

    •  Put bins with clear signs where people can reach them.

    •  Set up times to collect and send gloves to be recycled.

    •  Make sure gloves are clean and safe before recycling.

    •  Give rewards to get more people to join in.

Some programs, like VWR Glove Recycling and Kimberly-Clark Glove Recycling, take clean nitrile gloves. They use special places to turn old gloves into energy. This helps cut down on trash and saves money.

Sustainable Practices

INTCO Medical is a leader in making gloves that are better for the earth. They spend money to find new ways to make eco-friendly gloves. They make gloves that break down and weigh less. INTCO Medical has awards for being good to the planet and people. They use smart machines to make less waste and work faster. Other companies are doing the same because of rules and people wanting greener products.

Picking nitrile gloves from green companies helps keep workers safe and protects the earth.

Sustainability Certifications

When people pick between latex and nitrile gloves, they look at safety and how well the gloves work. They also check if the gloves have special green certifications. These certifications show that the gloves are good for the earth and people. INTCO Medical is a top company for getting Life Cycle Assessment (LCA) and carbon footprint certifications. These awards help workers pick gloves that are better for the planet.

LCA and Carbon Footprint

LCA means Life Cycle Assessment. It checks how gloves affect the Earth from start to finish. The carbon footprint tells us how much pollution each glove makes. Latex and nitrile gloves have different footprints because they use different materials and ways to make them. Companies like INTCO Medical use LCA facts to make gloves that are better for the earth.

Importance in Healthcare

Green certifications are very important in hospitals and clinics. These places use the certifications to make sure their glove makers care about the earth and people. Here are some good things about these certifications:

    •  Certifications like ISO and ISO check if glove makers do the right thing.

    •  They help hospitals follow rules like the EU’s Corporate Sustainability Reporting Directive and NHS Net Zero Strategy.

    •  They help hospitals run better and avoid trouble with the law.

    •  They make glove makers show where their gloves come from and how they are made.

Hospitals now ask glove makers to show green reports and certifications. This helps hospitals buy gloves that are safer for people and the planet. It also helps them reach their climate and health goals.

Professional Guidance

When professionals look at latex vs nitrile gloves, they need to think about many things. Safety and how well the gloves work are very important. The best glove depends on the job and where it is used. It also depends on what dangers are there. Picking the right glove means knowing the rules and paying close attention.

Selecting Nitrile Gloves

Professionals should use clear steps to pick gloves for each job:

    •  Intended Use: Decide if the gloves are for surgery, exams, or lab work.

    •  Compliance with Standards: Pick gloves that meet EN 374 and EN 455 rules.

    •  Glove Thickness: Thin gloves (3-5 mil) are good for careful hand work. Thick gloves (6-8 mil) give more protection.

    •  Fit and Sizing: Use a size chart to find the best fit.

    •  Glove Length: Longer gloves cover more skin for splash or soaking jobs.

    •  Grip and Texture: Gloves with textured fingers or palms help you hold things better.

    •  Powder-Free vs. Powdered: Powder-free gloves help stop allergies and keep things clean.

    •  Sterile vs. Non-Sterile: Sterile gloves are for surgeries. Non-sterile gloves are for regular jobs.

    •  Environmental Impact: Think about gloves that are better for the earth and have less waste.

Note: Not every glove stops all chemicals. Always check a chemical chart before using gloves.

Addressing Misconceptions

Some people believe things about gloves that are not true:

    •  Some think all gloves protect and feel the same. But gloves are different in how strong, bendy, and safe they are.

    •  Some think nitrile gloves never cause allergies. They are safer for most people, but a few can still react.

    •  Some think gloves last forever. But gloves break down faster in heat and sunlight.

    •  Taking off gloves the right way is very important. This helps stop germs from spreading.

Tip: Powder-free gloves help lower allergy risks and keep places safer.

Staying Informed

Professionals should always learn new things about gloves. They can:

    •  Go to classes and workshops.

    •  Read news from trusted groups.

    •  Check product labels and certifications.

    •  Look at chemical charts for each job.

    •  Learning more helps professionals pick the best gloves and stay safe at work.

2, More information on Nitrile Gloves: 

Nitrile Gloves are made from Nitrile Rubber.  

Nitrile rubber, also known as Buna-N, Perbunan, acrylonitrile butadiene rubber, and NBR, is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene. Trade names include Nipol, Krynac and Europrene.

Nitrile butadiene rubber (NBR) is a family of unsaturated copolymers of 2-propenenitrile and various butadiene monomers (1,2-butadiene and 1,3-butadiene). Although its physical and chemical properties vary depending on the polymer’s composition of nitrile, this form of synthetic rubber is unusual in being generally resistant to oil, fuel, and other chemicals (the more nitrile within the polymer, the higher the resistance to oils but the lower the flexibility of the material).

It is used in the automotive and aeronautical industry to make fuel and oil handling hoses, seals, grommets, and self-sealing fuel tanks, since ordinary rubbers cannot be used.[1] It is used in the nuclear industry to make protective gloves. NBR's ability to withstand a range of temperatures from −40 to 108 °C (−40 to 226 °F) makes it an ideal material for aeronautical applications. Nitrile butadiene is also used to create moulded goods, footwear, adhesives, sealants, sponges, expanded foams, and floor mats.

Its resilience makes NBR a useful material for disposable lab, cleaning, and examination gloves. Nitrile rubber is more resistant than natural rubber to oils and acids, and has superior strength, but has inferior flexibility. Nitrile gloves are therefore more puncture-resistant than natural rubber gloves, especially if the latter are degraded by exposure to chemicals or ozone.[citation needed] Nitrile rubber is less likely to cause an allergic reaction than natural rubber.

Nitrile rubber is generally resistant to aliphatic hydrocarbons. Nitrile, like natural rubber, can be attacked by ozone, ketones, esters and aldehydes.


Production

Krynac F nitrile rubber bales
Emulsifier (soap), 2-propenenitrile, various butadiene monomers (including 1,3-butadiene, 1,2-butadiene), radical generating activators, and a catalyst are added to polymerization vessels in the production of hot NBR. Water serves as the reaction medium within the vessel. The tanks are heated to 30–40 °C to facilitate the polymerization reaction and to promote branch formation in the polymer. Because several monomers capable of propagating the reaction are involved in the production of nitrile rubber the composition of each polymer can vary (depending on the concentrations of each monomer added to the polymerization tank and the conditions within the tank). One repeating unit found throughout the entire polymer may not exist. For this reason there is also no IUPAC name for the general polymer. The reaction for one possible portion of the polymer is shown below:

1,3-butadiene + 1,3-butadiene + 2-propenenitrile + 1,3-butadiene + 1,2-butadiene → nitrile butadiene rubber
Monomers are usually permitted to react for 5 to 12 hours. Polymerization is allowed to proceed to ~70% conversion before a “shortstop” agent (such as dimethyldithiocarbamate and diethyl hydroxylamine) is added to react with the remaining free radicals. Once the resultant latex has “shortstopped”, the unreacted monomers are removed through a steam in a slurry stripper. Recovery of unreacted monomers is close to 100%. After monomer recovery, latex is sent through a series of filters to remove unwanted solids and then sent to the blending tanks where it is stabilized with an antioxidant. The yielded polymer latex is coagulated using calcium nitrate, aluminium sulfate, and other coagulating agents in an aluminium tank. The coagulated substance is then washed and dried into crumb rubber.

The process for the production of cold NBR is very similar to that of hot NBR. Polymerization tanks are heated to 5–15 °C instead of 30–40 °C. Under lower temperature conditions, less branching will form on polymers (the amount of branching distinguishes cold NBR from hot NBR).

Properties
The raw material is yellow in color, though it can be orange or red tinted, depending on the manufacturer. Its elongation after fracture is ≥ 300% and possesses a tensile strength of ≥ 10 N/mm2. NBR has good resistance to mineral oils, vegetable oils, benzene/petrol, ordinary diluted acids and alkalines.

An important factor in the properties of NBR is the ratio of acrylonitrile groups to butadiene groups in the polymer backbone, referred to as the ACN content. The lower the ACN content, the lower the glass transition temperature; however, the higher the ACN content, the better resistance the polymer will have to nonpolar solvents as mentioned above. Most applications requiring both solvent resistance and low temperature flexibility require an ACN content of 33%.

Applications

A disposable nitrile rubber glove.
The uses of nitrile rubber include disposable non-latex gloves, automotive transmission belts, hoses, O rings, gaskets, oil seals, V belts, synthetic leather, printer's form rollers, and as cable jacketing; NBR latex can also be used in the preparation of adhesives and as a pigment binder.

Unlike polymers meant for ingestion, where small inconsistencies in chemical composition/structure can have a pronounced effect on the body, the general properties of NBR are not altered by minor structural/compositional differences. The production process itself is not overly complex; the polymerization, monomer recovery, and coagulation processes require some additives and equipment, but they are typical of the production of most rubbers. The necessary apparatus is simple and easy to obtain. For these reasons, the substance is widely produced in poorer countries where labor is relatively cheap. Among the highest producers of NBR are mainland China and Taiwan.

A hydrogenated version of nitrile rubber, HNBR, also known as HSN (highly saturated nitrile) is commonly used to manufacture o-rings for automotive air-conditioning systems.[3]

In January the European Commission imposed fines totaling €34,230,000 on the Bayer and Zeon groups for fixing prices for nitrile butadiene rubber, in violation of the EU ban on cartels and restrictive business practices (Article 81 of the EC Treaty and Article 53 of the EEA Agreement).[4]

Dangers
Use of these gloves when working with nitric acid or other strong oxidizers can be hazardous; the sample may spontaneously oxidize the gloves on contact, resulting in thermal and chemical burns from both the heat of oxidation and the caustic sample.[citation needed]

HNBR
Hydrogenated nitrile butadiene rubber (HNBR) is widely known for its physical strength and retention of properties after long-term exposure to heat, oil and chemicals. Trade names include Mill-Right ES (Garlock Klozure), Therban (Mobay) and Zetpol (Zeon Chemical).

Depending on filler selection and loading, HNBR compounds typically have tensile strengths of 20–31 MPa when measured at 23 °C. Compounding techniques allow for HNBR to be used over a broad temperature range, -40 °C to 165 °C, with minimal degradation over long periods of time. For low-temperature performance, low ACN grades should be used; high-temperature performance can be obtained by using highly saturated HNBR grades with white fillers. As a group, HNBR elastomers have excellent resistance to common automotive fluids (e.g., engine oil, coolant, fuel, etc.) and many industrial chemicals. Like NBR, fluid and chemical resistance improves as the ACN content is increased.[citation needed]

The unique properties and higher temperature rating attributed to HNBR when compared to NBR has resulted in wide adoption of HNBR in automotive, industrial, and assorted, performance-demanding applications. On a volume basis, the automotive market is the largest consumer, using HNBR for a host of dynamic and static seals, hoses, and belts. HNBR has also been widely employed in industrial sealing for oil field exploration and processing, as well as rolls for steel and paper mills.

XNBR
An improved version of nitrile butadiene rubber (NBR) is carboxylated nitrile butadiene rubber (XNBR). In this execution there are beside the sulfur bridges also carboxyl groups R-COO- on the double bond of the butadiene part. These groups will make ionic cross links with zinc (Zn2+) to give improved physical properties as compared to a non-carboxylated nitrile rubber. These ionic crosslinks are formed along with sulfur links. The carboxyl groups which are needed for these extra links are distributed randomly and are present at levels of 10% or less.

3, more detailed information for Medical gloves:

Medical gloves are disposable gloves used during medical examinations and procedures that help prevent contamination between caregivers and patients.[1] Medical gloves are made of different polymers including latex, nitrile rubber, vinyl and neoprene; they come unpowdered, or powdered with cornstarch to lubricate the gloves, making them easier to put on the hands.[2] Cornstarch replaced tissue-irritating Lycopodium powder and talc, but since even cornstarch can impede healing if it gets into tissues (as during surgery), unpowdered gloves are being used more often during surgery and other sensitive procedures. Special manufacturing processes are used to compensate for the lack of powder. There are two main types of gloves: exam and surgical. Surgical gloves have more precise sizing with a better precision and sensitivity and are made to a higher standard. Exam gloves are available as either sterile or non-sterile, while surgical gloves are generally sterile.

History
In William Stewart Halsted was the first to use sterilized medical gloves when he was at Johns Hopkins University.[4][5] With the publication of germ theory Halsted was using carbolic acid, introduced by Joseph Lister, to sterilize his hands and his nurse's hands. She was sensitive to the chemical, and it was damaging the skin on her hands; so he asked the Goodyear Tire and Rubber Company if they could make a glove of rubber that could be dipped in carbolic acid.

Glove materials

Latex

Neoprene
The first disposable latex medical gloves were manufactured in by Ansell. They based the production on the technique for making condoms.[6] These gloves have a range of clinical uses ranging from dealing with human excrement to dental applications.

Criminals have also been known to wear these gloves during the commission of their crimes. These gloves are often chosen because their thinness and tight fit allow for dexterity. However because of the thinness of these gloves, fingerprints may actually pass through the material as glove prints, thus transferring the wearer's prints onto whatever surface is touched or handled.[7][better source needed][8]

The participants of the Watergate burglaries infamously did so wearing rubber surgical gloves in an effort to hide their fingerprints.

Alternatives to latex
Main article: Latex allergy

Nitrile powder free gloves
Due to the increasing rate of latex allergy among health professionals, and in the general population, gloves made of non-latex materials such as vinyl, nitrile rubber, or neoprene have become widely used. Chemical processes may be employed to reduce the amount of antigenic protein in Hevea latex, resulting in alternative natural-rubber-based materials such Vytex Natural Rubber Latex. However, non-latex gloves have not yet replaced latex gloves in surgical procedures, as gloves made of alternative materials generally do not fully match the fine control or greater sensitivity to touch available with latex surgical gloves. (High-grade isoprene gloves are the only exception to this rule, as they have the same chemical structure as natural latex rubber. However, fully artificial polyisoprene—rather than "hypoallergenic" cleaned natural latex rubber[10]—is also the most expensive natural latex substitute available.[11]) Other high-grade non-latex gloves, such as nitrile gloves, can cost over twice the price of their latex counterparts, a fact that has often prevented switching to these alternative materials in cost-sensitive environments, such as many hospitals.[12] Nitrile gloves are made up of synthetic rubber. It has no latex protein content and more resisted to tear. Also it is very resistant to many chemicals and is very safe for people who allergic to latex protein.[13] We can say that nitrile glove is the most durable type of disposable gloves.[14] Although nitrile gloves are known for its durability, extra care should be taken while handling with tarnish silver and high reactive metals because those substances can react with sulfur, an accelerant in nitrile gloves.[13]

Powder-free medical gloves are used in medical cleanroom environments, where the need for cleanliness is often similar to that in a sensitive medical environment.[citation needed]

Double gloving
Double gloving is the practice of wearing two layers of medical gloves to reduce the danger of infection from glove failure or penetration of the gloves by sharp objects during medical procedures. A systematic review of the literature has shown double gloving to offer significantly more protection against inner glove perforation in surgical procedures compared to the use of a single glove layer.

4, A summary of important facts on Nitrile gloves 

Wearing Nitrile Gloves

Nitrile gloves are durable and can be worn for long periods of time before they start to break down. This can be a problem because your hands will become sweaty and any dirt particles that were on your hand before you put the glove on will start to irritate your skin after extended periods of wear. So change your nitrile gloves frequently during your work day to avoid this. 

Of course, it goes without saying, doctors, nurses, paramedics, dentists, tattoo artists and others who work in situations where blood or other bodily fluids are likely to be encountered, should change their gloves between clients. This applies to all types of gloves, not just nitrile gloves.

Nitrile Glove Ordering

Nitrile rubber is not quite as elastic as latex rubber. Because of this, it is really important to get the size right. If you are ordering for several people, order a case of each size. 

Keep your gloves fresh. If your gloves have been stored unopened in a cool, dry, dark environment, they should be good for up to two years after you have purchased them from ATOMO Dental If you have kept them longer than this, you should consider replacing your stock with fresh gloves. All gloves deteriorate over time and nitrile gloves are no exception. 

If you are confused about whether to order powdered or powder-free nitrile gloves, allow us to suggest that you try powder-free nitrile gloves first. Nitrile rubber is not as "sticky" as latex and many people do not have any trouble getting their nitrile gloves on and off. 

Nitrile gloves are powdered with two different types of powder:

• USP Cornstarch
• Calcium Carbonate

If you think there might be any issues with either of these substances within your working environment, then you will definitely need to order the powder-free variety. ATOMO Dental gloves are powdered only with the highest possible grade of cornstarch: 100% pure, USP edible cornstarch. If you are using your nitrile gloves in a medical environment where open wounds are frequently encountered, you should know that cornstarch has been recently found to occasionally inhibit healthy healing. 

Nitrile Glove Storage

Nitrile butadiene rubber gloves are the best type of gloves for use in high temperature environments.
