Hongjian Polymer
CM352 general-purpose 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, fine heat resistance, weatherability, flex resistance 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.
