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.
