EPDM. Ethylene-Propylene rubber has good resistance to ozone, steam, strong acids and alkal.It is not recommended for use with solvents and aromatic compounds.

 

CR. Neoprene, or polychloroprene, is a synthetic rubber that has physical properties closely resembling those of natural rubber. Has better weathering resistance than Natural Rubber and moderate resistance to oil, heat and ozone fluids.

 

SBR. Styrene-butadiene rubber is a synthetic rubber developed as an alternative to Natural Rubber. It is recommended for service in applications involving hot and cold water, air, steam, and some weak acids. SBR should not be used in applications involving strong acids, grease and chlorates. SBR offers little resistance to ozone and the majority of hydrocarbons.

 

Fluorine Rubber. has heat resistance up to 600°F and resistance to a wide range of oils and solvents; especially all aliphatic, aromatic, and halogenated hydrocarbons, acids, animal and vegetable oils.

 

Silicone rubber. Silicone rubber offers excellent resistance to the aging process. It is also unaffected by sunlight or ozone. Silicone rubber offers little mechanical resistance, and it does not resist aliphatic and aromatic hydrocarbons or steam. It is often used in applications involving hot air.

NBR. Nitrile rubber is also known as Buna-N. It offers good resistance to oils, and aliphatic hydrocarbons and gasoline. NBR offers little resistance to strong oxidant agents, chlorate hydrocarbons, ketones and esters.

 

IIR. Butyl rubber is a blend of polymers mixed with isoprene.  Butyl rubber is a very good general purpose rubber for many applications. Butyl rubber is known for its excellent impermeability to gases. This characteristic, together with its flexibility and weather resistance, makes it a habitually-used rubber for numerous industrial applications. Butyl rubber is also essential for seals and protection in chemical industries where high concentrations of mineral acids and alkalis occur such as phosphate plants, fertilisers, caustic soda, etc.

 

Hypalon. CSM (Chlorosulphonated Polyethylene) has superior resistance to weather, ozone and oxidation; excellent resistance to alkalies and acids.

 

NR. Natural rubber has high elasticity and excellent wear resistance and impact resistance, and it is also very resistant to tearing. However, it is not recommended for use in oil and high temperature environments.
