CAS 63231-66-3 CPE 135A IMPACT MODIFIER FOR PVC Profile With High
Tensile Strength
Description:
Chlorinated Polyethylene (CPE) is a new type of themo-plastic
elastomer based on chlorination reaction. CPE is of white color,
nontoxic and odorless. Its special structure makes it possess
various superior physical and chemical performances. Now CPE has
been widely used in plastics and rubber applications, and is well
acknowledged by the customers for its superior comprehensive
performances and ideal cost-effectiveness.
Characteristic:
Chlorinated polyethylene (CPE) is a saturated polymer material with
a white powder appearance. It is non-toxic and tasteless. It has
excellent weather resistance, ozone resistance, chemical resistance
and aging resistance. It has good oil resistance, flame retardancy
and coloring. performance. Good toughness (flexibility at -30 °C),
good compatibility with other polymer materials, high decomposition
temperature, decomposition to produce HCL, HCL can catalyze the
dechlorination of CPE.
Chlorinated polyethylene is a polymer material obtained by
high-density polyethylene (HDPE) by chlorination substitution
reaction. Depending on the structure and use, chlorinated
polyethylene can be divided into resin chlorinated polyethylene
(CPE) and elastomeric chlorinated polyethylene (CM). The
thermoplastic resin may be used alone or in combination with a
resin such as polyvinyl chloride (PVC), polyethylene (PE),
polypropylene (PP), polystyrene (PS), ABS or even polyurethane
(PU). In the rubber industry, CPE can be used as a high
performance, high quality specialty rubber, or with ethylene
propylene rubber (EPR), butyl rubber (IIR), nitrile rubber (NBR),
chlorosulfonated polyethylene (CSM), etc. Other rubber blends are
used.
Application:
PVC Modification
used in various rigid plastic products such as plastic profiles,
pipes, fittings and sheets, and it is used in production of
external wall sidings and anti-corrosive and moisture-proof thin
wall boards.
Flame Retardant ABS
Modifying PE and other Plastics
The structure of CPE has similar molecule chains with PE and other
plastics, therefore it has good adaptibility with them. After
addition of CPE, the hardness of the plastic product can be
decreased effectively and weatherability, ozone resistance and
flame retardancy can be increased.
