Ethylene Propylene Diene Monomer rubber is a copolymer of ethylene, propylene and a small amount of non-conjugated diene. It is a kind of ethylene propylene rubber and is represented by EPDM, It is excellent in aging resistance such as ozone, heat resistance, weather resistance and so on because its main chain is a chemically stable saturated hydrocarbon and It consists of only unsaturated double bonds in the side chain. It has a wide range of applications
Advantages
Good weather resistance and ozone resistance
Excellent water resistance and chemical resistance
Suitable for alcohols and ketones
High temperature steam resistance, low gas permeability
EPDM can be used in applications as follow：
Weak acid
Alkali
Hot water and steam.
Inorganic acids and a variety of organic acids
Silicone oil and silicone ester
Multiple polar solvents (alcohols, ketones, esters)
EPDM can not be used in applications as follow：
Animal fats
Aromatic or aliphatic carbohydrates
Concentrated acids
Therefore, the diaphragms of this material is particularly suitable for use in the field of hygienic treatment requiring steam sterilization and oxidizing media.
