9090M (highest diene 14.1 %)

EPDM (Ethylene-Propylene Diene Rubber)

Mitsui EPT 9090M is ethylene-propylene-diene terpolymer (EPDM) synthesized by Metallocene Catalyst.
This polymer is non oil-extended EPDM with high Mooney viscosity which is designed for excellent extrude ability, injection mold ability and mechanical strength.
This grade is suitable for extruded products and for molded

– High Mooney viscosity
– Medium ethylene content
– Heat and UV stability
– Amorphous

– High load compounding is possible
– Excellent low temperature property
– High mechanical strength
– Excellent extrudability
