Ethylene propylene diene rubber (EPDM)
EPDM rubber is produced by copolymerisation of ethylene, propylene and a diene and can be crosslinked with sulphur or peroxides. Crosslinking with peroxides produces vulcanisates with improved compression set. EPDM has good oxygen, ozone and temperature resistance. The bondability of EPDM is greatly reduced due to its structure (ethylene, propylene). EPDM is characterised by above-average chemical resistance, but its resistance to mineral oil and grease is rather poor.
