Trilene® CP-80

High viscosity and low molecular weight Ethylene-Propylene (EPDM) liquid Copolymer for use in elastomers and lubricants.
Product Overview
Trilene® CP-80 is an Ethylene -Propylene
liquid Copolymer that is used as a plasticizer in rubber compounds. Unlike the Trilene® terpolymers, CP-80 does not crosslink with the resin but can still offer the benefit of a non-blooming plasticizer without degrading the mechanical properties of the compound. It is less viscous compared to the terpolymers and can be used in applications that need FDA approval. Trilene® CP-80 can also be used in lubricants as a thickener providing good shear properties and low temperature flexibility.
