Chlorinated Polyethylene (CPE) 135A is a high-performance polymer additive widely utilized across various industries, primarily as an impact modifier for Polyvinyl Chloride (PVC) and other plastics. Its unique composition and properties make it an indispensable component for enhancing product durability, flexibility, and resistance to environmental factors. As a leading manufacturer and supplier of chemical auxiliaries, we provide detailed insights into the properties and applications of CPE 135A, helping you make informed procurement decisions.

Key Properties of CPE 135A:

  • Chemical Composition: CPE 135A is produced by chlorinating polyethylene, typically yielding a product with a chlorine content of around 35%. This chlorination process modifies the polyethylene's structure, imparting it with elastomeric qualities and improved compatibility with polar polymers like PVC.
  • Impact Modification: Its primary function is as an impact modifier. CPE 135A effectively absorbs and dissipates impact energy, significantly improving the toughness and reducing the brittleness of rigid plastics. This is crucial for products that undergo mechanical stress or impact during their lifecycle.
  • Low-Temperature Flexibility: A significant advantage of CPE 135A is its excellent flexibility at low temperatures. This ensures that products remain pliable and functional even in cold environments, preventing premature failure due to embrittlement.
  • Weatherability and UV Resistance: CPE 135A exhibits outstanding resistance to weathering, ozone, and UV radiation. This property is vital for outdoor applications, helping to maintain the material's integrity, color, and mechanical properties over extended periods.
  • Flame Retardancy: The chlorine content in CPE 135A also contributes to its inherent flame-retardant properties, enhancing the safety of finished products, particularly in applications like wire and cable jacketing.
  • Chemical Resistance: It offers good resistance to a range of chemicals, acids, and alkalis, making it suitable for applications exposed to corrosive environments.
  • Processing Ease: CPE 135A is known for its good processability. It can be easily blended with PVC and other polymers, allowing for efficient extrusion, injection molding, and calendering processes.

Primary Applications of CPE 135A:

The versatile properties of CPE 135A lend themselves to a wide range of applications:

  • PVC Pipes and Fittings: Enhances impact strength and durability.
  • PVC Profiles: Improves weatherability and impact resistance for window frames, doors, and siding.
  • Wire and Cable Jacketing: Provides flame retardancy, flexibility, and abrasion resistance.
  • Automotive Components: Used in hoses, seals, and interior parts for its chemical resistance and flexibility.
  • Films and Sheets: Increases toughness and weather resistance for various sheeting applications.
  • Rubber Applications: Can be blended with other elastomers to improve specific properties.
