PVC Additives Toughen agent Chlorinated Polyethylene 135A Imact Modifier For PVC Pipe
Property:
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.
Use:
CPE has two series of thermoplastic resin and elastomer rubber. The thermoplastic CPE resin can be used alone or for blending with polyvingl-chloride(PVC)polyethylene (PE) polypropyrene(PP) polystyrene(PS) ABS or polyurethane(PU) etc. The elastomer CPE rubber shows both the elasticity of rubber and the resistance to oilchemicalheatcold and flame etc. Of plastics. The CPE as a special rubber with high performance can be used alone for rubber industry or for blending with EPDMLIRNBR or CSM 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.
