High Grade Chlorinated Polyethylene PVC Impact Modifier Excellent
Weather Resistance Chlorine 36%
Properties:
Chlorinated polyethylene ( CPE) is made from high density
polyethylene(HDPE) replaced by chlorination reaction of elastic
polymer materials. The appearance is non toxic and odorless white
powder. 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, CPE can
be used as impact modifiers, plastic modified solubilizer and
synthetic special rubber.
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.
Feature:
Excellent weather resistance, ozone resistance, chemical resistance
and flame retardant, with a variety of plastics rubber has good
compatibility
Effectively improve the toughness of rigid PVC products, anti-red
and anti-aging properties,
Improve the melting point of PVC, has a good plasticizing
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.
