Lion Elastomers Trilene® 77 is a low molecular weight Ethylene Propylene (EPDM) terpolymer with 10.5% diene content for use in rubber, coating, and adhesive formulations.
Lion Elastomers Trilene® 77 grade is a crystalline waxy EPDM terpolymer that is used as an additive in rubber compounds and works well in sulfur-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® 77 EPDM is used as a nonpolar, non crystalline elastomeric material that provides strong adhesion to a variety of substrates. Additionally, Trilene® 77 demonstrates low permeability to gases and water vapor, superior impact resistance and high flexibility at low temperatures. Trilene® 77 EPDM is easier to handle during mixing compared to Trilene® 65 and 67 since it is a solid at room temperature.
