CHLORINATED POLYETHYLENE(CPE 135B)
–Rubber type: As synthetic rubber in wire & cable, hose products.
This product is a kind of amorphous elastomer with minimal crystal. It has lower Mooney viscosity and mastication temperature as well as excellent properties such as good processing property, excellent weathering resistance, good flex resistance and flame resistance. It can be blended with CR, CSM, NBR, EPDM, SBR and NR at any ratio.
It is white powder and innocuous. Since hydrogen atoms are replaced by chlorine atoms ,the crytallization of HDPE was destroyed and becomes soft and full of rubber property.Because of the presence of chlorine atom, CPE turns into polar polymers and have the same polar groups as PVC. Under this situation, it increases the compatibility of PVC. In addition,it can blend with PE, PS and rubber to improve its physical properties.
