High enb polymer

EPDM rubber (ethylene propylene diene monomer rubber) is a type of synthetic rubber that is used in many applications. Dienes used in the manufacture of EPDM rubbers are ethylidene norbornene (ENB), dicyclopentadiene (DCPD), and vinyl norbornene (VNB). 4-8% of these monomers are typically used. … Ver mais Relative to rubbers with unsaturated backbones (natural rubber, SBR, neoprene), rubbers with saturated polymer backbones, such as EPDM, exhibit superior resistance to heat, light, and ozone exposure. … Ver mais • Thermoplastic vulcanizates (mixtures of vulcanized polymers such as EPDM and immiscible polymers such as polypropylene).
