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)
PROPERTIES
– Low Mooney viscosity
– Medium ethylene content
– High ENB content
– Precisely controlled long chain branching
FEATURES
– Easy mixing and processing
– Good flexibility at the low temperature
– Excellent foam ability
