EPDM is with excellent allround properties. It is of many advantages, for example, outstanding anti-ozone, excellent weather resistance, outstanding chemical resistance, resistent to polar reagent like brake fluid,strong acid and alkali,alcohol and so on.
The disadvantage is expanding too much in the ordinary mineral oil and second ester lubricating oil.
Temperature range：-60℃~+150℃.
