Trilene® 65

Low molecular weight liquid Ethylene Propylene (EPDM) terpolymer with 10% diene content for use in rubber, coatings and adhesives.
Product Overview
Trilene® 65 is a liquid EPDM terpolymer that is used as an additive in rubber compounds and works well in peroxide-cured systems to reduce viscosity. It acts as a reactive plasticizer in rubber compounds without any significant loss of hardness or other mechanical properties. In coatings & adhesives Trilene® 65 is used as a nonpolar, non crystalline elastomeric material that provides strong adhesion to a variety of substrates. Additionally, Trilene® 65 demonstrates low permeability to gases and water vapor, superior impact resistance and high flexibility at low temperatures.
