Chlorinated polyethylene CPE135A is mainly used as an impact modifier in PVC pipes to improve the impact strength, temperature resistance, weather resistance, delamination performance, and cold resistance of the products.

Chlorinated polyethylene (CPE) is a material made by chlorination of high-density polyethylene (HDPE), which has excellent properties such as heat oxidation resistance, ozone resistance, weather resistance, oil resistance, flame retardancy, and chemical resistance. CPE has a high molecular weight, good mechanical properties, and good compatibility with PVC resin powder, which can significantly improve the impact strength of products at low temperatures. In addition, CPE also has excellent wear resistance, flexural flexibility, and other superior properties that have not been mentioned, making it an ideal choice for PVC pipe modifiers. ‌

In the production and application of PVC pipes, the role of CPE135A is mainly reflected in the following aspects:

Improving impact resistance: CPE135A can significantly enhance the impact resistance of PVC pipes, especially under normal and low temperature conditions, enhancing the safety and durability of the pipes.

Improving temperature and weather resistance: The addition of CPE135A can significantly enhance the temperature and weather resistance of PVC pipes, enabling them to maintain stable performance under a wider range of environmental conditions.

Enhanced delamination performance and cold resistance: In addition, CPE135A also helps to improve the delamination performance and cold resistance of PVC pipes, further optimizing the processing and use conditions of the pipes.

In summary, the application of chlorinated polyethylene CPE135A in PVC pipes not only improves the physical properties and chemical stability of the pipes, but also broadens the scope and service life of PVC pipes, making it a very important PVC modifier.
