Chlorinated Polyethylene Resin

As an excellent impact modifier, Keliren® chlorinated polyethylene thermoplastic resin is widely used in PVC extrusion and injection molding products, including profiles, pipes, sheets and fittings. The addition of a small amount of Keliren® resin can greatly enhance the impact resistance of rigid PVC and improve its processing fluidity. In addition, due to its good chemical resistance, outstanding low-temperature performance, high filling capacity, excellent weather resistance and remarkable compatibility, Keliren® resin is used in a wider range of formulation systems.

Application fields

  • CPE is currently the most widely used and most economical impact modifier in the PVC profile industry.

  • Keliren® resin is able to improve the impact resistance and aging properties of PVC pipes significantly. CPE is especially widely used in large-diameter pressure-resistant liquid conveying pipes to improve its pressure bearing performance and extend its service life.

  • When Keliren® resin is blended with PVC to produce soft products, CPE acts as a permanent polymer plasticizer for PVC to avoid the migration of general plasticizers (such as DOP) .

  • Keliren® resin is also used as a modifier and compatibilizer in flame retardant ABS, SAN, HDPE and PP materials to improve their impact resistance and flame retardancy.

  • Keliren® resin is also used in the sole industry due to its good wear resistance and flex resistance.
