EPDM rubber (ethylene propylene diene monomer rubber), a type of synthetic rubber, is an elastomer characterized by a wide range of applications. This is an M-Class rubber where the 'M' in M-Class refers to its classification in ASTM standard D-1418; the M class includes rubbers having a saturated chain of the polyethylene type. Dienes used in the manufacture of EPDM rubbers are dicyclopentadiene (DCPD), ethylidene norbornene (ENB), and vinyl nor- bornene (VNB). EPDM rubber is closely related to ethylene propylene rubber: ethylene pro- pylene rubber is a copolymer of ethylene and propylene, whereas EPDM rubber is a terpolymer of ethylene, propylene and a diene-component (Figure 2).

Elastomeric Polymers
Published in Kathleen Hess-Kosa, Building Materials, 2017
Ethylene polypropylene diene monomer (EPDM) rubber, a thermoset elastomeric terpolymer, is produced by the polymerizing ethylene, propylene, and a small percentage of diene. In commercial use rubbers, the diene represents 4%–5% by weight and the ethylene represents 30%–70% by weight of the polymer. The higher the ethylene content, the more the hardness and tensile strength. Solid, as opposed to liquid, EPDM is vulcanized with sulfur and/or other equivalent accelerators.

Ethylene propylene diene rubber or EPDM (Ethylene Propylene Diene Type M ASTM) is a thermopolymer elastomer that has good resistance to abrasion and wear. The composition of this material contains between 45% and 75% ethylene, being in general more resistant when the percentage of ethylene is higher. The main characteristics of EPDM rubber are its resistance to aging, weathering and high temperature, as well as ozone and oxidation. All these characteristics make it appropriate to be used in antivibration elements that require a thermal resistance, since it withstands a maximum temperature of 150°C when it works in discontinuous way.
