Chlorinated Polyethylene
Chlorinated Polyethylene (CPE) is a highly versatile thermoplastic elastomer derived from the chlorination of high-density polyethylene (HDPE). This process imbues CPE with a unique set of properties, making it an indispensable additive in the modification of Polyvinyl Chloride (PVC) and other polymers. Its primary function is to significantly improve the impact strength and flexibility of rigid PVC products, while also contributing to enhanced weatherability, oil resistance, and flame retardancy.
- Explore the benefits of chlorinated polyethylene in PVC, where it acts as a crucial impact modifier, enhancing the toughness of rigid PVC products.
- Discover how CPE's excellent weatherability makes it ideal for outdoor applications, ensuring long-term product integrity.
- Learn about the good oil and flame resistance properties of CPE, contributing to safer and more durable end products.
- Understand how chlorinated polyethylene improves the low-temperature performance of PVC, preventing brittleness in cold conditions.
Advantages Offered by CPE
Enhanced Impact Resistance
The use of CPE as an impact modifier in PVC formulations dramatically increases the material's ability to withstand impact, reducing the likelihood of fracture or breakage in finished products.
Superior Weatherability
CPE exhibits excellent resistance to UV radiation and weathering, ensuring that products maintain their mechanical properties and aesthetic appeal even when exposed to outdoor environmental conditions.
Improved Chemical and Oil Resistance
The chemical structure of CPE provides robust resistance to oils, greases, and various chemicals, making it suitable for demanding industrial applications where exposure to such substances is common.
Key Applications
PVC Profiles and Pipes
Leveraging CPE's capabilities to improve impact strength and flexibility, it is widely used in the manufacturing of PVC window profiles, pipes, and fittings, enhancing their durability and processing ease.
Wire and Cable Jacketing
The flame retardant and oil resistant properties of CPE make it an excellent choice for wire and cable jacketing, providing protection and ensuring electrical safety in various environments.
Hoses and Tubing
CPE's combination of flexibility, oil resistance, and weatherability makes it ideal for industrial hoses and automotive tubing, where performance and longevity are critical.
Seals and Gaskets
Its excellent compression set resistance and chemical compatibility allow CPE to be used effectively in seals and gaskets, ensuring reliable performance in demanding sealing applications.
