PVC Impact Modifier HIGH GOOD QUALITY HOT SALE CHLORINATED
POLYETHYLENE CPE 135A
Properties:
Chlorinated Polyethylene, or CPE, is a very promising
thermalplastic material widely used as PVC impact modifier in the
world. It can greatly improve the shock-resistance and tensile
properties of PVC products. Besides this, CPE is also used in
building materials, rubber industry, electronic machinery,
biomedicine, agriculture, packaing, paint, textile industry and
packaing.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.
The product is no rules structure of the saturated thermoplastic
resin, its appearance is white powder; it can be mixed and used
with PVC, evidently increasing the impact resistance strength in
lower temperature, flame resistance, ageing resistance and flexure
performance.
CPE135A mainly used in products such as window profiles, pipes,
pipefittings, extrusion board, and also used in magnetic materials,
such as magnetic rubber strips and all type of flattened magnet.
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.
Use:
It is applicable for PVC profile, non-conventional PVC, PVC pipe,
PVC pipe fittings. It is also used for the soft products together
with PVC, EVA or paracril.
