Ethylene Propylene Diene Rubber (EPDM)

EPDM O-rings

EPDM O-rings from COG

The range of uses of peroxydically cross-linked EPDM includes in hot water and steam seals. EPDM O-rings are also very resistant to ageing and ozone. Compared with the usual types of synthesis natural rubber it has good resistance to cold temperatures. O-rings made out of EPDM is not resistant to aliphatic or aromatic hydrocarbons or mineral oil products. Resistance to chemicals, and also to oxidising agents, is very good. Temperature range from -50 °C to +140 °C depending on type.
