Ethylene Propylene Diene Monomer (EPDM)

The E refers to ethylene, P to propylene, D to diene. The M class includes rubbers having a saturated chain of the polymethylene type. Dienes currently used in the manufacture of EPDM rubbers are dicyclopentadiene (DCPD), ethylidene norbornene (ENB), and vinyl norbornene (VNB). EPDM rubber is closely related to ethylene propylene rubber (EPM). EPM is a copolymer of ethylene and propylene whereas EPDM is a terpolymer of Ethylene, Propylene and a ‘Diene-Component’.

 

Grades of EPDM are:

 

Oil Extended EPDM

Non-Oil Extended EPDM

 

Uses: EPDM rubber is used in seals, glass-run channels, radiators, garden and appliance hose, tubing, washers, belts, electrical insulation, vibrators, and speaker cone surrounds. It is also used as a medium for water resistance in electrical cable-jointing, roofing membranes, geomembranes, rubber mechanical goods, plastic impact modification, thermoplastic, vulcanizates, and many other applications

The main properties of EPDM are its outstanding heat, ozone and weather resistance. The resistance to polar substances and steam are also good. It has excellent electrical insulating properties.
