Ethylene propylene rubber is made by copolymerization of ethylene and propylene. Its main chain does not contain double chains. Therefore, it has excellent heat resistance, aging resistance, ozone resistance and chemical stability. It is resistant to freon and a variety of coolants. The general operating temperature range is - 50 ~ 150 ℃. It has excellent resistance to polar solvents such as alcohol, ketone, glycol and phospholipid hydraulic oil.
Advantage:
Good weather resistance and ozone resistance
Excellent water resistance and chemical resistance
Alcohol and ketone can be used
High temperature vapor resistance, good impermeability to gas
Disadvantages:
It is not recommended for food use or exposure to aromatic hydrogen.
Application fields:
Seals for high temperature water vapor service.
A seal or part of a fixture.
Refrigerator, seal in refrigeration equipment.
