- CPE features
- For thermoplastic resins applications CPE-can be calendered, injection
molded or extruded into tough ,chemical , weather
and flame resistant end product. Also provide built-in ignition resistance.
For elastomer and rubber applications CPE -can upgrade the properties
of the other thermoplastics, improve their
resistance to impact, chemicals, flame, weathering etc.
-
- Other features including
-
Excellent low temperature properties
Inherent flexibility without plasticization
flame & chemical & weather &ozone resistance
Good response with commercial heat and light stabilizers
Excellent acceptance of high filler levels and heat/light stabilizers
Ability to be processed on wide range of conventional fabrication
equipment
Excellent compatibility with PVC, polyethylene ,styrene/ acrylonitrile
, ABS, ethylene vinyl acetate and others.

CPE features in synthetic rubber
CPE or CM ideally used for mixing with other rubbers to reduce production
cost,
CPE or CM rubber chemical resistance better than EPDM, NBR, SBR.
CPE or CM heat resistance better than Butyl , CR,EPDM,NR,NBR,SBR.
CPE or CM oil resistance better than Butyl , CR, EPDM, NR , SBR.
CPE or CM flame resistance better than EPDM,NBR
CPE or CM ozone resistance better than CR,NBR
CPE has characteristics which are good for use on low voltage flexible
cables (such as HPN cord) at lower cost than neoprene or hypalon.
CPE is cold, oil and heat resistant, as well as flame retardant. In
the case of HPN cord CPE acts as insulation and jacket combined.
Chlorinated polyethylene (CPE) modifier for PVC window profile or
other PVC rigid profiles can be used alone or blending at any ratios
with Acrylic based or methacrylate-butadiene-styrene MBS based impact
modifier - PVC Window profile , adding CPE can improved weatherability
on MBS based impact modifiers and further enhance cold temperature
resistance on Acrylic based impact modifier. Normally CPE/ACR or CPE/MBS
blend at 50 /50 ratio.
Our cm422 used as migration free plasticized films, profiles, roofing
membrane, auto sector such as flexible PVC sheet.
CPE352 modification of polyethylene and polypropylene to in prove
flame retardancy, mechanical property and resistance ageing, weather
for cables with superior electrical property
CM422 blending with PVC are also widely applied. CPE as permanent
high molecular-plasticizer for PVC could successfully avoid migration
effect by common plasticizers.
CPE is superior in abrasion resistance and has long flexing life
and is widely used in production of soles .
- CPE Processing tips
- Compare chlorinated polyethylene (CPE), with other impact modifiers
like acrylic (ACR) ,methacrylate-butadiene-styrene
(MBS), and acrylonitrile-butadiene-styrene (ABS) polymers are normally
used to modify impact strength of PVC. CPE. As
flux promoters, tend to reduce the temperature of the extruder barrel
needed for a given melt temperature so when
compounding PVC. we suggest temperature should be increased slightly
higher compare with other impact modifiers.
