CAS 63231-66-3 PVC Additives CPE 135A Ozone Resistance

Product Description

PVC Additives CPE 135A Chlorinated Polyethylene Imact Modifier For PVC Pipe

Property:

Chlorinated polyethylene is our main product which is a kind of white solid powder by low voltage high density polyethylene. It is the main PVC impact modifier with double performance of the plastic and rubber. This product has good weatherability, oil resistance, ozone resistance, flame resistance and good histocompatibility with varied plastics and rubber. It can effectively improve toughness and impact resistance and anti-aging of rigid PVC products, to increase the melting point of PVC.

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.

Features:
1) Good anti-aging property and excellent weatherability. It could be used under harsh climate and environment. And it is fully resistant to ozone.
2) Good anti-combustion, no self ignition.
3) Good low temperature flexibility. It could remain flexible under –20. It may be used as impact modifier in UPVC product.
4) Excellent endurances to chemicals. It is inert to many chemical reagents and corrosion resistant to various acids and alkalis.
5) Good processing ability. It is easy to be shaped.
6) Extremely safe for operation. CPE is harmless to human body and the environment.
7) Excellent stability.

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.
