(Ethylene Propylene Diene Monomer) rubber has excellent resistance to ozone, sun and oxygen. Peroxide cured EPDM can be used in applications where temperature ranges from -53ºC to 150ºC (-65F to 302F). Available in Economy grade, High grade and Peroxide Cure grades - Durometer ranges from 40-80.
Trade names - Dutral*, Nordel®, Vistalon*
(Isobutylene-isoprene copolymer) rubber is predominately used for inner tubes of pneumatic tires and in vacuum and high pressure applications. It has excellent resistance to weathering, oxygen, heat and ozone. Temperature ranges from -37.2ºC to 82.2ºC (-35F to 180F).
This rubber has excellent resistance to uv / ozone and most chemicals, but has poor fuel resistance. Chlorosulphonated Polyethylene is one of the most weather-resistant elastomers available. Temperature ranges -28.9ºC to 98.9ºC (-20ºF to +210ºF).
Trade names - Hypalon®
(cis-polyisoprene) – This rubber has good creep and stress relaxation resistance and is low cost. It’s main disadvantage is lack of resistance to oxygen and ozone/uv. Temperature ranges: -51.1ºC to 93.3ºC (-60ºF to +200ºF)
This material provides excellent resistance to oil, chemical and heat and is used in a wide range of applications. It also offers high uv and ozone resistance. This rubber is also available for FDA applications. Temperature ranges: -40ºC to 115.6ºC (– 40ºF to +240ºF).
Trade names - Neoprene polychlorprene
Silicone (and fluorosilicone) Rubber:
Features high / low temperature resistance and superior compression set. It is also resistant to UV/Ozone, offers excellent aging characteristics and is fungus resistant. Silicone rubbers are available in different grades and for FDA applications. Durometer ranges 30 – 80. Temperature ranges: -53.9ºC to 232.2ºC (– 65ºF to +450ºF)
Styrene Butadiene Rubber (SBR):
This rubber has similar properties to Natural Rubber. It has excellent abrasion resistance, impact strength and high tensile strength. Temperature ranges: -40ºC to 82.2C (– 40ºF to +180ºF)
This rubber offers excellent resistance to oils, solvents, petroleum-based hydraulic fluids and fuels. It also performs well in both hot and cold temperatures and provides good resistance to hydrocarbon solvents, and very good resistance to alkalis and acids. Durometer ranges 40 – 90. Temperature ranges:-51.1ºC to 115.6ºC (– 60ºF to +240ºF).
This rubber has excellent resistance to heat, oil, and concentrated acids. Viton has exceptional performance in very hot and extremely corrosive environments. It was originally introduced for use in the aerospace industry and is now used in many other industries, including the automotive, appliance, and fluid power. Temperature ranges:-28.9ºC to 232.2ºC (– 20ºF to +450ºF)
Cloth Inserted rubber (SBR, Neoprene, EPDM, Buna-N) is a rubber sheet with a polyester, nylon, cotton, or fiberglass fabric impregnated in the rubber. This material improves stability in flanged gasket applications under high compression loads.
