For professionals in the plastics industry, optimizing material performance is paramount. Chlorinated Polyethylene, specifically the CPE 135A grade, stands out as a critical additive for enhancing Polyvinyl Chloride (PVC) products. As a leading manufacturer and supplier, understanding its properties is key to unlocking better product outcomes.

What is CPE 135A?

CPE 135A is a thermoplastic elastomer produced through the chlorination of high-density polyethylene (HDPE). This process imbues the material with a unique combination of properties that make it an exceptional impact modifier. It typically appears as a white powder, boasting excellent resistance to weathering, ozone, chemicals, and flame. Its molecular structure, free from double bonds, contributes to its superior aging resistance.

The Role of CPE 135A in PVC Formulations

PVC, while versatile, can be inherently brittle. This is where CPE 135A plays a crucial role. When incorporated into PVC formulations, it significantly improves:

  • Impact Strength: CPE 135A absorbs and dissipates impact energy, preventing PVC products from cracking or shattering, especially during low-temperature conditions. This makes it indispensable for applications like PVC pipes, window profiles, and fittings that endure physical stress.
  • Flexibility and Toughness: It imparts a rubbery characteristic to rigid PVC, enhancing its flexibility and overall toughness without compromising its structural integrity.
  • Processing Stability: The good compatibility of CPE 135A with PVC and other polymers aids in smoother processing, leading to more efficient production cycles and consistent product quality. Manufacturers often look for reliable suppliers in China to source this critical component.
  • Weatherability and Flame Retardancy: Its inherent resistance to UV radiation, ozone, and flame makes it an ideal choice for outdoor applications and products requiring enhanced safety features.

Why Choose a Reputable CPE 135A Supplier?

When you are looking to buy CPE 135A, partnering with a dependable manufacturer is essential. A quality supplier ensures consistent product specifications, which is vital for achieving predictable performance in your PVC products. They can also provide technical data sheets and support to help you optimize your formulations. The price of CPE 135A per ton can vary, making it important to secure competitive pricing from a trusted source.

In conclusion, CPE 135A is more than just an additive; it's a performance enhancer. Its ability to significantly improve the impact resistance, flexibility, and durability of PVC products makes it a sought-after material for a wide range of industries. For any manufacturer aiming to produce high-quality, resilient PVC goods, sourcing premium CPE 135A is a strategic investment.
