Natural rubber exhibits exceptional elongation, excellent tear strength, good wear resistance and recovery properties. It exhibits goods resistance to most inorganic salts, ammonia, mild acids and alkalies. Natural rubber does not offer good resistance oils and solvents and is not recommended where exposure to ozone, oxygen or sunlight is prominent. Temperature range -50 to 120 Deg (-60 to 250 Deg F). Neoprene offers excellent oil resistance, low permeability to gases and resistance to ozone, weathering and corrosion. The material is suitable for moderate acids, alkalies, salt solutions, petroleum and commercial oils and fuels. It is considered unsuitable for use with strong acids, fats. greases and most hydrocarbons. Temperature range -50 to 110 Deg C (-60 to 230 Deg F).
Nitrile is a synthetic rubber offering improved chemical resistance and temperature capabilities to Neoprene. The material offers good resistance to oils and solvents, aromatic and aliphatic hydrocarbons, petroleum oils and gasoline's, animal fats and lacquer solvents. it offers poor resistance to strong oxidising agents, chlorinated hydrocarbons, ketones and esters. Temperature range -50 to 120 Deg C (-60 to 250 Deg F).
Butyl, otherwise known as isobutylene or isopena, is a elastomer offering excellent resistance to wear, tear and general abrasions as well as good ozone and gas permeatation resistance, suitable for mild acid and alkali service esters, butyl offers little resistance to commercial oils and fuels. Temperature range -40 to 150 deg C (-40 to 300 Deg F)
Viton (fluorinated Hydrocarbon) offers excellent resistance to acids, altphatic hydrocarbons, oils, gasoline and many corrosive industrial applications. The materials offer excellent resistance to temperature, weathering and gas permeability. It is not suitable for use against amines, esters, ketones, steam or low temperature service. Temperature range -20 to 200 Deg C (-4 to 392 Deg F)
EPDM offers goods resistance to ozone, heat, steam, strong acids and alkalis. It is not suitable for use in oils, solvents and aromatic hydrocarbons. Temperature range -50 to 150 Deg C (-60 to 300 Deg F).
The silicone range of rubbers offer excellent high and low temperature properties, far superior to any other grade. They are unsuitable for use against steam and many hydrocarbons. Temperature range -70 to 250 Deg C (-95 to 480 Deg F).
