High Temperature Gasket Materials

All Seals offers premium solid rubber and sponge rubber materials suitable for high temperature applications, such as: Silicone, Fluorosilicone, Fluorocarbon (Viton™), EPDM, Viton™ Sponge, Silicone Sponge,Conductive Silicone and Silicone Coated Fiberglass. They are among the best high temperature performers in regards to elastomeric materials. Each has an operating temperature range specific to the material.

Viton® Sponge plays a particularly vital role in cases where soft fluoroelastomers are desirable. The practical low hardness limit for solid Viton™ is 55 durometer. Viton™ Sponge fills this void where softer material is required however the heat and fluid resistance of solid Viton™ is necessary.

Silicone Sponge offers improved durability and sealing. It is used to seal or protect various outdoor communication, lighting or electronic enclosures, while providing protection against small dust particles, wind driven rain or fire. Silicone sponge offers higher tear and tensile strength than lighter grade sponge materials. (UL Rated Material: UL-94VO)

Viton® Rubber is a high performance rubber compound designed for use when it is necessary to contain fluids that would degrade normal elastomers.

All Seals also recommends additional high temperature material options, including: Compressed Non-Asbestos, Fiberfrax® Ceramic Fiber, PTFE (Teflon®), Flexible Graphite & Carbon, Nomex®, andKapton®.

Compressed Non-Asbestos Gaskets (Temperatures to 850°F)

Compressed non-asbestos gasket materials combine non-asbestos fibers such as fiberglass and aramid fibers with rubber to enhance the temperature and pressure performance of the gasket. Combining inorganic and organic fibers with rubber and fiberglass allows for a range of variants that have different mechanical specifications. Metal inserted materials are able to operate at even higher pressure and temperatures. Compressed non-asbestos materials are the most standard form of high-temperature gaskets. They can be used in general applications that do not require high levels of complexity and endurance.

All Seals offers Garlock®, Thermoseal® (Klinger®), Flexitallic®, Frenzelit®, Durlon® and Teadit® brands of compressed non-asbestos gasket materials. These materials are available in thicknesses ranging from 1/64" to 1/4" thick.

Fiberfrax® Ceramic Fiber Gaskets (Temperatures to °F)

Fiberfrax® is a light weight, resilient asbestos free gasket material which has excellent thermal characteristics. It is made from an Alumina-Silica combination. It possesses high temperature stability, low thermal conductivity, low heat storage, thermal shock resistance, and combines the high heat resistance of refractory ceramics with the weight and resiliency of paper. It is easy to handle, and can be die-cut to any shape or size. Fiberfrax® has low shrinkage, good dielectric properties and has excellent corrosion resistance. Its temperature tolerance ranges from ºF to ºF, depending on the grade of material.

Teflon®-Based Gaskets (Temperatures to 600°F)

Teflon® (PTFE) based gasket materials are the most universal gasket material available. It is able to withstand more aggressive chemical environments than traditional non-asbestos gasket materials. Expanded PTFE has the same properties as PTFE, plus it is much more compressible. This allows for sealing even with difficult gasket applications having irregular or rough surfaces. Metal inserted and expanded PTFE are able to operate at higher pressures than standard Teflon® (PTFE) gaskets. These materials are available in thicknesses 1/32" through 1/4".

Flexible Graphite & Carbon Gaskets (Temperatures to °F)

Flexible Graphite and Carbon gaskets are able to withstand more aggressive chemical environments and higher pressures than standard compressed non-asbestos gasket materials. Sheets can be laminated with 316 stainless steel foil with tang or wire inserts for various applications and are able to operate at even higher pressures. Grafoil® has outstanding resistance to corrosion against a wide variety of acids, alkalis & salt solutions, organic compounds, and heat transfer fluids. Pure graphite can handle temperatures up to °F. All Seals carries Garlock®, Thermoseal® and Grafoil® brands of carbon and graphite based gasket materials. These materials are available in thicknesses 1/32" through 1/4".
