Material

  • Ethylene Propylene Diene Monomer (EPDM) has good resistance to weathering, ozone, UV, electricity, oils, water, steam and some solvents. It is temperature resistant to 220 F.
  • Fluorosilicone is resistant to ozone, weathering, detergent, salt water, engine and transmission oil, non-petroleum brake fluid, hydraulic fluids that resist fire, vegetable and animal oils, high molecular weight chlorinated aromatic hydrocarbons, and has better mineral oil, fuel, and aromatic hydrocarbons (benzene) compatibility than silicone. Fluorosilicone is acceptable for temperature applications between -100 degrees F (-73 degrees C) to 350 degrees F (177 degrees C). Like silicone, fluorosilicone is vulnerable to mechanical wear and tear, water and steam over 250 degrees F (121degrees C), chlorinated hydrocarbons (trichloroethylene), acids and bases, and hydrocarbon fuels.
  • Highly Saturated Nitrile Halogenated Acryonitrile Butadiene (HNBR) is a rubber with excellent abrasion, tear, and impact resistance. It has good resistance to dilute and organic acids, alcohols, oils, some fuels and poor resistance to solvents and esters.
  • Neoprene, or polychloroprene, is a synthetic rubber with good chemical stability that maintains flexibility over a wide temperature range.Neoprene (polychloroprene) can have a high tensile strength, and has abrasion, tear, and compression set resistance. It is generally fire resistant and compatible for use with ozone, sunlight, ammonia, Freon, and some hydrocarbons. It also had good adhesion to metal and is often used in metal to rubber bonding applications. Neoprene is vulnerable to ketones, acids, brake fluids and phosphate esters.
  • Nitrile is a synthetic polymer that has good compression set, abrasion, tear, solvent and oil resistance. It also has good adhesion to metals, and can function across a wide temperature range (-40 to 250 F). Nitrile has poor resistance to weathering and sunlight, and should not be used with polar solvents, ozone, and some hydrocarbons.
  • Polytetrafluoroethylene (PTFE) resists chemicals, moisture, and high temperatures. It is often used for electrical applications.
  • Polyurethane is flexible, resistant to weathering, tears, oils, fuels, impact, abrasion, and can withstand a wide temperature range of -95F to 185F.
  • Silicone rubber is nonreactive, flexible, and resistant to high temperatures. Silicone is resistant to ozone, weather, detergent, salt water, engine and transmission oil, non-petroleum brake fluid, hydraulic fluids that resist fire, vegetable and animal oils, and high molecular weight chlorinated aromatic hydrocarbons. Silicone is vulnerable to mechanical wear and tear, water and steam over 250 degrees F/121 degrees C, aromatic hydrocarbons (benzene), chlorinated hydrocarbons (trichloroethylene), acids and bases, and hydrocarbon fuels.
  • Viton (fluorocarbon elastomer) has heat, fuel, and chemical resistance and is compatible for use with non-flammable hydraulic fuels, silicone oil, chlorinated hydrocarbons (trichlorethylene), fuels, aromatic hydrocarbons (benzene) and aliphatic hydrocarbons (propane), as well as high vacuum environments, ozone, and weathering. Viton is vulnerable to low molecular organic acids, ammonia gas, alkalis, amines, glycol-based brake fluids, and super-heated steam.
