8030M (low density sponge grade)

EPDM (Ethylene-Propylene Diene Rubber)

Mitsui EPT “8030M” is ethylene-propylene-diene terpolymer (EPDM) synthesized by Metallocene Catalyst.
“8030M” is non oil-extended EPDM which is designed for good processing and foam ability.
This grade is suitable for low density sponges, when used independently or blended with other EPDM (3092M, 3072EM, 4045M)

– Low Mooney viscosity
– Medium ethylene content
– High ENB content
– Precisely controlled long chain branching


– Easy mixing and processing
– Good flexibility at the low temperature
– Excellent foam ability
