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.
