1, PVC Modification
As a superior and cost-effective impact modifier, CPE is widely used in various rigid plastic products such as plastic profiles, pipes, fittings and sheets, and it is used in production of external wall sidings and anti-corrosive and moisture-proof thin wall boards. CPE is able to speed up plastification of PVC, improve its processibility, greatly enhance the impact resistance of the final product and greatly improve PVC’s low temperature performances and weatherability.
2, Flame Retardant ABS
CPE itself is a type of flame retardant and it has great adaptability with flame retardant ABS. The use of it can decrease the amount of flame retardant used, increase the filling capacity while not decrease the impact resistance of the flame retardant products.
3, Magnetic Material
Magnetic product made from CPE has superior magnetic power and the rubber product made from CPE has good low temperature flexibility and ductility. They are widely used for fridge sealing strips, magnetic boards, magnetic bars, etc. The good heat resistance of CPE also makes it applied in production of magnetic components for electromechanical products.
4, Soft Product
As an outstanding elastomer, CPE can be directly used for production of soft products. By using CPE, no plasticizer or small amount of plasticizer is added. The soft product produced has particularly nice weatherability and long service life. The use of CPE successfully avoids serious plasticizer migration in traditional PVC soft products which leads to physically negative transformation of the final products, and successfully extend the service life of the soft products. It can be widely used in water-proof coils, shoe materials, plastic wires, sealing strips, tarpaulin, awning and other soft products.
5, Modifying PE and other Plastics
The structure of CPE has similar molecule chains with PE and other plastics, therefore it has good adaptibility with them. After addition of CPE, the hardness of the plastic product can be decreased effectively and weatherability, ozone resistance and flame retardancy can be increased.
