General Properties of Elastomers
www.elbex-us.comEPDM (Ethylene-Propylene-Diene Modified) GENERAL DESCRIPTION: There are two basic types of EP rubber available in today's market—EP and EPDM. EP is a copolymer of ethylene and propylene, while EPDM is a terpolymer combining ethylene, propylene and a diene monomer. EP uses a peroxide cure system. EPDM uses a sulfur cure system.

Chemical Resistance Guide - Gilson Eng
www.gilsoneng.comEPDM - (EPM) is an elastomer made from ethylene-propylene diene monomer. EPDM has good abrasion and tear resistance and offers excellent chemical resistance to a variety of acids and alkalines. It is susceptible to attack by oils and is not re com-mended for applications involving petroleum oils, strong acids or strong alkalines.
