At NINGBO INNO PHARMCHEM CO.,LTD., we are constantly seeking innovative solutions to improve material performance. One such crucial material we focus on is Chlorinated Polyethylene (CPE). Specifically, CPE 135A has emerged as a highly effective additive, significantly enhancing the properties of Polyvinyl Chloride (PVC). This article delves into the reasons why CPE 135A is indispensable in modern PVC formulations and the benefits it brings to various applications.

What is Chlorinated Polyethylene (CPE) 135A?

Chlorinated Polyethylene (CPE) is a type of thermoplastic elastomer produced by chlorinating high-density polyethylene. CPE 135A, in particular, is a grade designed to offer a balance of properties that make it an ideal modifier for PVC. Its unique, irregular molecular structure, coupled with a specific chlorine content (typically around 35-36%), allows it to integrate seamlessly with PVC, improving its overall performance without compromising its inherent characteristics. When sourcing high-quality CPE 135A, looking for reliable suppliers is key to ensuring consistent results in your manufacturing processes.

Enhancing PVC Properties with CPE 135A

The primary role of CPE 135A in PVC applications is as an impact modifier. It effectively increases the toughness and impact strength of rigid PVC products, making them less brittle and more resilient. This is particularly important for products like window profiles, pipes, and siding, which are often subjected to mechanical stress and environmental fluctuations. The benefits of CPE 135A in PVC are manifold:

  • Improved Impact Resistance: CPE 135A significantly boosts the impact strength of PVC, making it ideal for applications requiring durability.
  • Enhanced Toughness: It imparts a desirable level of toughness, reducing the likelihood of cracking or breaking.
  • Superior Weatherability: CPE 135A provides excellent resistance to weathering, UV radiation, and ozone, extending the lifespan of PVC products exposed to the elements. This is a key reason why weather resistant PVC additive is sought after.
  • Flame Retardancy: The material also offers good flame retardant properties, enhancing the safety of the final product. The demand for flame retardant PVC additive is continuously growing.
  • Good Chemical Resistance: CPE 135A exhibits strong resistance to various chemicals, oils, and solvents, making it suitable for demanding environments. This makes it a valuable chemical resistant PVC modifier.
  • Improved Processing Fluidity: By modifying the melt behavior of PVC, CPE 135A can improve extrusion processes, leading to smoother finishes and more efficient production. This addresses the need for improving PVC processing fluidity.

Applications of CPE 135A

The versatility of CPE 135A allows it to be used in a wide array of PVC applications. Beyond rigid PVC profiles and pipes, it is also a preferred additive for:

  • Wire and Cable Jacketing: Its insulation properties, combined with flame retardancy and flexibility, make it ideal for cable sheathing.
  • Automotive Components: Used in hoses, tubes, and seals where resistance to oil, chemicals, and temperature fluctuations is critical.
  • General Polymer Modification: It can also be blended with other polymers like ABS and PE to enhance their properties.

When considering the price of CPE 135A, it's important to weigh the enhanced performance and extended product life it provides against the initial investment. Sourcing reliable CPE 135A for PVC applications is crucial for achieving optimal results.
