The plastics industry constantly seeks materials that offer enhanced performance without compromising on processing efficiency or cost-effectiveness. For Polyvinyl Chloride (PVC), a versatile but inherently brittle polymer, impact modification is key to unlocking a wider range of applications, from construction materials to consumer goods. Chlorinated Polyethylene (CPE), particularly the widely used CPE 135A grade, has become an indispensable impact modifier for PVC. As a leading manufacturer and supplier of advanced polymer additives, we are proud to offer high-quality CPE 135A that significantly elevates PVC product performance.

CPE 135A functions as a toughening agent by improving the impact strength and ductility of rigid PVC. When incorporated into PVC formulations, it forms a finely dispersed rubbery phase within the plastic matrix. This dispersed phase acts as an energy absorber during impact, effectively preventing crack initiation and propagation. The result is a PVC product that can withstand greater impact forces and is less prone to shattering, especially at lower temperatures.

The benefits of using CPE 135A as a PVC impact modifier are manifold:

  • Improved Impact Strength: This is the primary advantage. PVC products modified with CPE 135A exhibit significantly higher Izod and Charpy impact strengths, making them suitable for demanding applications like pipes, pipe fittings, window profiles, and automotive components.
  • Enhanced Low-Temperature Performance: CPE retains its flexibility at low temperatures, ensuring that the impact resistance of modified PVC is maintained even in cold environments. This is crucial for outdoor applications and components used in colder climates.
  • Good Processability: CPE 135A offers excellent compatibility with PVC resins and other additives, allowing for seamless integration into existing PVC processing methods such as extrusion, injection molding, and calendering. Its consistent particle size and melt characteristics contribute to stable processing and high-quality finished products.
  • Excellent Weatherability and Chemical Resistance: Beyond impact modification, CPE imparts superior resistance to UV radiation, ozone, chemicals, and oils, further enhancing the durability and lifespan of PVC products exposed to environmental stresses.
  • Flame Retardancy: The inherent flame-retardant properties of CPE contribute to the overall safety of the final PVC product, especially important for building materials and electrical applications.
