PVC Impact Modifier CPE 135A / CPE Resin CAS No 63231-66-3 High
Density
Product Description:
CPE is odourless nontoxic and white or pale yellow powder with
excellent resistance to weathering or age ozone chemicals, and good
resistance to oil or flame. It is a colourable material with very
good tenacity (flexible at -30 a brittle temperature under -70),
and good miscibility with various polymers due to its properties of
both plastics and rubber. CPE shows excellent resistance to very
low temperature or high (a decomposition temperature above 160).
Characteristic:
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:
CPE135A Have excellent toughness, weather resistance, oil
resistance, flame retardant, coloring resistance, chemical and
other properties, is compatible with plastics, rubber, excellent
filling properties. Depending on the product performance. widely
used in rigid PVC products, such as PVC profile, pipe, pipe
fittings, sheet and wire etc.
