Polyethylene wax for PVC pipes

Polyethylene wax for PVC pipes

Polyethylene wax is extensively employed in the production of PVC pipes. Throughtout the mixing process, it uniformly dispersed with PVC resin to establish a stable system. As the mixture undergoes heating and melting, a chemical reaction takes place between the two materials, resulting in a new compound. This compound transforms into a homogeneous melt that gradually cools and solidifies, forming PVC pipes.

Roles of polyethylene wax(PE) in PVC pipe production:

Internal and External Lubricant: Polyethylene wax serves as a highly effective lubricant, providing exceptional internal and external lubrication. It significantly reduces adhesion between the resin and mold, minimizes friction during extrusion, and enhances material flow. In PVC pip production, polyethylene wax plays a critical role in reducing friction between the melt and equipment, thereby improving melt fluidity, pipe molding speed, and production efficiency.

  • Thermal Stabilizer: Polyethylene wax exhibits thermal stability, effectively redusing thermal degradation of PVC pipes during high-temperature processing, enhancing their stability. The inherent stability of polyethylene wax makes it an ideal compound for improving the durability and longevity of PVC pipes.
  • Impact Modifier: Adding polyethylene wax to PVC pipe production can enhance the toughness, elasticity, and impact resistance, increasing the pipe's service life.
  • Dispersing Agent: In the production of PVC pipes, polyethylene wax disperses pigments and additives, enhancing their coloring effect and creating a more uniform color.
  • Brightening Agent: Polyethylene wax improves the surface gloss of PVC pipes, enhancing their aesthetic appearance.
  • Plasticizing Speed improvement: With its high melting point, polyethylene wax accelerates the plasticizing speed of PVC, improves metal stripping, and creates smoother pipe surfaces.
  • Heat-Resistant Performance Improvement: Renowned for its exceptional heat-resistant properties, polyethylene wax enhances the heat resistance of PVC pipes, enabling them to maintain functionality in high-temperature environments and significantly extending their service life.
  • Transparency Improvement: The implementation of minuscule polyethylene wax particles effectively surface unevenness in polyvinyl chloride (PVC) pipes. reducing light scattering and reflection, ultimately improving transparency.
  • Anti-Static Properties: The polyethylene wax molecular chain, containing carbonyl and hydroxyl groups, is compatible with fillers, pigments, and polar resins. providing anti-static properties due to its high melting point and low viscosity.
  • Protection Against Environmental Damage: Polyethylene wax forms a protective film on the surface of PVC pipes, effectively preventing the intrusion of moisture, oxygen, and other harmful substances, thus safeguarding the pipes from external environment damage and extending their service life.

In conclusion,Polyethylene wax has become an indispensable component in PVC pipe production. Offering numerous advantages such as improved processing performance, heat resistance, impact resistance, transparency, and protection against external environmental damage. Due to these benefits, polyethylene wax is widely adopted in the manufacturing of PVC pipes.
