EPDM is a mixture of Ethylene, Propylene, and Diene with monomer chemical binding. The content of ethylene is around 45% to 85%. The content of dienes is around 2.5% – 12%. If you want higher loading possibilities, better mixing plus extrusion, you can choose the ethylene with higher content which is around 65% – 85%. The common dienes used in EPDM rubber are DCPD (dicyclopentadiene), ENB (ethylidene norbornene), and VNB (vinil norbornene).

The chemical properties of EPDM rubber are the appearance, hardness, tensile failure stress, elongation after fracture, and density. The hardness value is around 40 to 90. The tensile failure stress is 25 Mpa in ultimate. The elongation after fracture is more than and equal to 300%. The density of this EPDM can be compunded from 0.9 to more than 2 gram per centimeter cubics.
