Ethylene-propylene rubber by polymerization of ethylene and propylene co backbone without double bonds, so it has very excellent heat resistance, aging resistance, resilience, insulation performance, stability, ozone resistance and low temperature performance, but can not use sulfur vulcanization. To solve this problem, introducing a small amount in the main chain of the third component of the double bond and may sulfur vulcanized EPDM Serve. Polar solvents such as alcohols, ketones, glycols and phosphoric lipids excellent hydraulic fluid resistance.
Temperature range: -55 ℃ ~ 125 ℃, the use of organic peroxide vulcanization up to 150 ℃.

Benefits:
Good weather resistance and anti-ozone resistance
Excellent water resistance and anti-chemical
Alcohols and ketones can be applied
High temperature vapor, low gas permeability
High-temperature water vapor seals Environment
Sanitary equipment seals or parts
Brake (brake) system Rubber Parts
Radiator (car radiator) seals

Cons:
Not recommended for use in food or exposure to aromatic hydrocarbons
Medium:
Hot water and steam
Glycol-based brake fluid, brake fluid silicon
Variety of organic and inorganic acids
Detergents, soda, potassium hydroxide
Phosphate ester hydraulic fluids
Silicone and silicon ester
More polar solvents (alcohols, ketones, esters)
NA medium: mineral oil, fuel oil.
