For product formulators and procurement specialists in the chemical and plastics industries, understanding the specific attributes of additives is key to developing high-performance materials. Chlorinated Polyethylene (CPE) 135A is a prime example of such an additive, widely recognized for its ability to enhance the properties of PVC and other polymers. As a specialist manufacturer and supplier, we provide deep insights into the chemical and physical advantages that make CPE 135A a preferred choice.

Understanding the Chemistry of CPE 135A
CPE 135A is produced by the chlorination of high-density polyethylene (HDPE). This process substitutes hydrogen atoms on the polyethylene chain with chlorine atoms. The resulting polymer is saturated, which contributes to its excellent thermal stability and resistance to degradation. The degree of chlorination, typically around 35% for CPE 135A, dictates its compatibility with PVC and its effectiveness as an impact modifier. Its molecular structure allows it to integrate well into PVC matrices, creating a toughened network that absorbs energy.

Key Chemical and Physical Properties of CPE 135A
When you buy CPE 135A, you are investing in a material with a valuable set of properties:

  • Excellent Toughness: CPE 135A significantly boosts the impact strength of rigid PVC, preventing brittle fracture.
  • Low-Temperature Flexibility: It maintains its flexibility and impact resistance even at sub-zero temperatures, crucial for outdoor applications.
  • Weatherability: Offers good resistance to UV radiation and weathering, extending product lifespan.
  • Oil and Chemical Resistance: Its saturated polymer structure provides excellent resistance to oils, chemicals, and solvents.
  • Flame Retardancy: CPE 135A inherently possesses flame-retardant properties, enhancing product safety.
  • Good Compatibility: It exhibits excellent compatibility with PVC, ABS, PP, and other resins, acting as a bridge between different polymer phases.
  • Processing Aid Functionality: In addition to impact modification, it can improve melt processing characteristics, reduce melt fracture, and enhance extrusion rates.

As a leading CPE 135A supplier, we ensure that our product consistently meets these specifications, providing reliable performance for your formulations.

Benefits for PVC Product Manufacturers
Integrating CPE 135A into PVC formulations yields substantial benefits for manufacturers:

  • Enhanced Product Durability: Reduces product failure rates due to impact or environmental stress.
  • Wider Application Range: Enables the use of PVC in more demanding environments, including outdoor and low-temperature applications.
  • Improved Processing Efficiency: Can lead to faster processing speeds and reduced energy consumption due to its processing aid properties.
  • Cost-Effectiveness: Offers a high-performance solution at a competitive price point, especially when sourced from a China manufacturer.

The ability to purchase high-quality CPE 135A from a reliable supplier is critical for companies aiming to optimize their product performance and manufacturing costs.

In summary, the unique chemical and physical properties of CPE 135A make it an indispensable additive for improving the performance and applicability of PVC products. Its contribution to toughness, flexibility, and resistance properties ensures that end-products are durable and reliable, meeting the stringent demands of various industries.
