Chlorinated Polyethylene (CPE) for rigid PVC impact modifier and ABS Impact modifier is white powder material used in hard, semi-hard and soft PVC industries. using this type of additive improves melt strength, impact properties, high thermal resistance, atmospheric resistance, reduces die swelling, and good color stability. This additive reduces or eliminates the adhesion to the roller surface and speeds up the movement of the melt in the extrusion and creates a uniform surface in the product. The main applications of impact modifiers can be in extruded profiles in PVC doors and windows, PVC rolled sheets and films, PVC pipes and fittings, production parts of injection and blow molding, pipes PVC duct and PVC foam pointed. It is suggested that the consumption rate be considered from 0.5 to 5.0 (phr) depending on the formulation and process conditions.
