Trilene® 67
Low-molecular weight liquid ethylene propylene (EPDM) terpolymer has 9.5% diene content and is used in rubber, coatings and adhesives.
Lion Elastomers Trilene® 67 is a liquid EPDM terpolymer used as an additive in rubber compounds, and works well in sulfur-cured systems to reduce viscosity. It behaves as a reactive plasticizer in rubber compounds without any significant loss of hardness or other mechanical properties. Trilene® 67 is used as a nonpolar, non crystalline elastomeric material that provides strong adhesion to a variety of substrates. Additionally, Trilene® 67 demonstrates low permeability to gases and water vapor, superior impact resistance and high flexibility at low temperatures.
