For manufacturers working with Polyvinyl Chloride (PVC), achieving optimal processing conditions and superior final product quality is a continuous pursuit. Chlorinated Polyethylene (CPE) 135A plays a crucial role in this endeavor, acting not only as an impact modifier but also as a processing aid. As a dedicated supplier of industrial chemicals, we understand the importance of this additive in streamlining manufacturing and elevating product standards.

CPE 135A: Beyond Impact Modification

While CPE 135A is widely recognized for its ability to enhance impact strength and low-temperature flexibility in PVC, its benefits extend to the processing stage. The introduction of CPE 135A into PVC formulations can improve melt strength and stability. This is due to its unique molecular structure, which includes chlorine atoms, allowing for better compatibility and interaction with the PVC matrix. With a typical chlorine content of 35±1% and a molecular formula of [CH2-CHCl-CH2-CH2]n, CPE 135A is meticulously manufactured to support optimal processing.

How CPE 135A Aids PVC Processing

Product formulation scientists and engineers will find several advantages when using CPE 135A during the manufacturing process:

  • Improved Melt Strength: CPE 135A can enhance the melt strength of PVC compounds, reducing the risk of sagging or deformation during extrusion processes, such as those used for profiles and pipes. This improved melt stability leads to more consistent product dimensions.
  • Enhanced Thermal Stability: While not a primary stabilizer, CPE 135A can contribute to the overall thermal stability of PVC formulations when properly processed, helping to prevent premature degradation during high-temperature operations.
  • Better Dispersion: Its compatibility with PVC aids in achieving a more uniform dispersion of other additives within the PVC matrix, leading to a more consistent final product with predictable properties.
  • Surface Finish: The inclusion of CPE 135A can contribute to a smoother surface finish in extruded PVC products, improving aesthetics and market appeal.
  • Reduced Processing Issues: By improving melt characteristics and compatibility, CPE 135A can help mitigate common processing challenges, leading to higher yields and reduced waste.

Key Applications Benefiting from Improved Processing

The processing benefits of CPE 135A are particularly valuable in:

  • PVC Profiles and Extrusions: Ensuring cleaner cuts, better shape retention, and smoother surfaces for window profiles, door frames, and decorative trims.
  • PVC Pipes and Fittings: Improving the consistency of extruded pipes and the moldability of fittings, crucial for plumbing and infrastructure applications.
  • PVC Sheets and Films: Facilitating smoother calendering and extrusion processes for producing high-quality sheets used in construction and packaging.
