CPE is a synthetic material produced by chlorinating polyethylene, resulting in enhanced heat resistance, chemical resistance, and high flexibility. It is categorized into two main grades: elastomer grade and plastic grade. The elastomer grade is used for products requiring flexibility and durability, such as rubber hoses, seals, and waterproof tarpaulins. The plastic grade is often used as an impact modifier in PVC to improve toughness.
Key properties of CPE include excellent resistance to ozone, chemicals, and UV radiation, as well as flame resistance in certain grades. It performs well in outdoor applications and is compatible with other materials such as PVC, NBR, and EPDM. Common applications include cables, automotive parts, construction materials, and industrial fabrics. Compared to other synthetic rubbers, CPE offers a good balance of performance and cost, providing durability and long service life in harsh environments.
