NINGBO INNO PHARMCHEM CO.,LTD. is a trusted supplier of advanced chemical additives, and our Polyethylene Wax (PE Wax) is a cornerstone product for optimizing the processing of Polyvinyl Chloride (PVC). PVC processing is notoriously sensitive to friction and melt characteristics, making effective lubrication and controlled fusion essential for producing high-quality pipes, profiles, films, and other components. PE wax plays a multifaceted role, significantly enhancing efficiency and product outcomes.

PVC processing requires a careful balance of internal and external lubrication to manage melt flow, prevent degradation, and ensure a good surface finish. PE wax excels in both these roles, offering distinct advantages:

  • Internal Lubrication: As an internal lubricant, PE wax reduces the friction between PVC polymer chains. This leads to a lower melt viscosity, improved melt strength, and better melt homogeneity. The result is smoother processing, reduced energy consumption, and a lower risk of degradation during extrusion or molding. This is particularly beneficial for rigid PVC applications where maintaining melt stability is crucial.
  • External Lubrication and Fusion Control: PE wax also acts as an external lubricant, reducing the friction between the PVC melt and the hot metal surfaces of processing equipment, such as extruders and molds. This prevents sticking, minimizes plate-out, and reduces the need for frequent cleaning. Furthermore, specific grades of PE wax, particularly oxidized types, can act as fusion promoters or controllers. They help in achieving the optimal balance of fusion (gelation) and plasticization, leading to improved mechanical properties and enhanced surface gloss of the final PVC product.
  • Improved Surface Finish: The lubricating action of PE wax significantly contributes to achieving smooth, high-gloss surfaces on PVC products like pipes, profiles, and films. This enhanced surface finish not only improves aesthetics but can also contribute to better performance characteristics, such as reduced drag or improved cleanliness.
  • Processing Aid for PVC Compounds: PE wax is an excellent processing aid for various PVC compounds, including those with high filler loadings or recycled content. It helps to maintain consistent melt flow and prevents issues like sticking or poor dispersion, ensuring that even challenging formulations can be processed efficiently.
  • Enhanced Thermal Stability: While not a primary stabilizer, PE wax can contribute to the overall thermal stability of PVC compounds by facilitating smoother processing at lower temperatures or with reduced shear, thereby mitigating thermal degradation.
