Ipmact Modifier CPE Chlorinated Polyethylene For PVC Pipe Fittings
White Powder CPE Chlorinated Polyethylene 135A imact Modifier For PVC Pipe Fittings
Property:
It is chloridized by HDPE. Due to the molecule of CPE does not contain double bond, it has excellent weatherability, anti-flaming and wide application. It is mainly used as PVC impact modifier.
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:
CPE 135A is designed for general purpose plastic impact modification where superior impact strength, good low temperature property and high filler acceptance are required. This grade is the most popular grade for plastic impact modification. The application fields cover PVC door and window profiles, siding, sheet, fence, pipe, electrical conduit etc.
Storage:
Should be stored in a cool, dry and ventilated place to prevent moisture, exposure, storage and transportation to avoid contamination, storage period is one year, after which they passed the test can still be used.
