Hongjian Polymer
CM352L low Mooney chlorinated polyethylene (CPE) rubber compound
1.product characteristics
This product is a kind of saturated thermoplastic elastomer with irregular structure, almost no crystal. It features lower plasticizing temperature and Mooney viscosity, excellent processing flowability, good heat resistance, weatherability, flex durability and flame retardancy. It not only can be used as halogen rubber alone but also can be used with CR、CSM、NBR、SBR、NR and so on together by mixing in random proportion.
