High quality chemical auxiliary agent CPE 135A chlorinated polyethylene CAS No 63231-66-3
Description Of CPE 135A:
CPE 135A is a high molecular copolymer made from polyethylene and chlorine with linear molecular structure. It has excellent effect on weather-resistance, flame retardance, chemical-resistance and ozone-resistance.It is one of the main copolymer used for PVC products such as PVC door and window profiles, sheet, pipe, and more
Product performance:
It is white powder and innocuous. Since hydrogen atoms are replaced by chlorine atoms, the crystallization 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 has 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.
Application Of CPE 135A:
1. PVC window profile
2. U-PVC pipe
3. Cable tray
4. Thermoplastic & ABS
5. PVC sheet
