Ethylene propylene-diene monomer (EPDM) forms a noncrystallizing copolymer with a low Tg. The percentages of PP and PE units determine their properties. The Tg of EPDM is − 60°C for PE/PP of 67/33 to 50/50 percentages. It is an unsaturated polymer since PP and PE are saturated and restrict crystal formation. crystal nicole facebookEPDM rubber (ethylene propylene diene monomer rubber) is a type of synthetic rubber that is used in many applications.
