In the realm of plastics manufacturing, the efficiency and quality of the extrusion process are critical determinants of success. For companies working with Polyvinyl Chloride (PVC), achieving optimal melt flow and smooth surface finish can be a challenge. This is where specialized additives such as Chlorinated Polyethylene (CPE) 135A play a vital role, acting not only as an impact modifier but also as a valuable processing aid. As a premier manufacturer and supplier of chemical auxiliaries and catalysts in China, we are dedicated to providing materials that enhance your production capabilities.

Understanding the Role of Processing Aids in PVC Extrusion

PVC, by nature, has a relatively high melt viscosity and a narrow processing window, which can sometimes lead to issues like melt fracture, poor surface finish, and reduced output rates. Processing aids are additives designed to improve these characteristics by enhancing melt strength, promoting fusion, reducing melt fracture, and improving the flow of the molten polymer. Effective processing aids contribute to better product quality, increased throughput, and reduced manufacturing costs.

Chlorinated Polyethylene CPE 135A: A Dual-Action Additive

While widely recognized for its impact modification properties, our industrial-grade Chlorinated Polyethylene CPE 135A also excels as a processing aid for PVC. Its unique molecular structure and composition offer several advantages that directly benefit the extrusion process:

  • Improved Melt Flow and Extrudability: CPE 135A helps to lower the melt viscosity and improve the overall flow behavior of PVC compounds. This leads to easier extrusion and allows for higher processing speeds without compromising the structural integrity or surface finish of the extruded profiles.
  • Enhanced Fusion Characteristics: It promotes faster and more uniform fusion of PVC particles, ensuring a homogenous melt. This is crucial for achieving dense, defect-free products.
  • Reduced Melt Fracture: By improving the viscoelastic properties of the melt, CPE 135A helps to mitigate melt fracture, a phenomenon that can lead to surface irregularities and aesthetic defects in extruded products like window profiles and pipes.
  • Increased Production Efficiency: The combined effect of improved flow, fusion, and reduced defects translates directly into increased production efficiency, lower scrap rates, and potentially reduced energy consumption.

Applications Where CPE 135A Shines in Extrusion

The benefits of using CPE 135A as a processing aid are particularly evident in the manufacturing of:

  • PVC Window and Door Profiles: Achieving sharp edges, smooth surfaces, and dimensional stability is critical. CPE 135A aids in the smooth extrusion of complex profiles.
  • PVC Pipes and Conduits: Uniform wall thickness and smooth inner and outer surfaces are essential. CPE 135A contributes to better extrusion control.
  • PVC Siding and Cladding: The aesthetic appeal and durability of siding are enhanced by efficient extrusion processes facilitated by CPE 135A.
  • Plastic Sheets and Films: For applications requiring high-quality surface finish and dimensional accuracy, CPE 135A is an invaluable additive.
