Why Do PVC Products Use Oxidized Polyethylene Wax(PE Wax)?

Why do PVC products use oxidized polyethylene wax? PVC processing is a technical job. If you want to produce good PVC products, then the balance of internal and external lubrication is indispensable. Choose different lubricant combinations according to the terminal products, which must be able to produce long-term, stable, and high-yield products, while meeting cost requirements.

1. PVC transparent products, such as PVC heat shrink film. Because non-polar polyethylene wax and PVC are incompatible, highly transparent PVC products cannot be produced, while polar oxidized polyethylene wax can effectively avoid affecting transparency and improve demolding performance.
2. PVC foam products, unlike conventional solid hard product PVC extrusion, the dynamic foaming molding process has higher requirements for PVC plasticization and melt strength. By adding oxidized polyethylene wax, the quality of plasticization and foaming can be improved, and the surface finish can be improved.
3. Especially thick PVC products, such as the production of ultra-thick PVC pipes, have higher requirements for plasticization, and oxidized polyethylene wax can effectively increase the plasticization speed of production.
4. Particularly thin PVC products, such as PVC decorative films, require higher demoulding performance during the production process, and oxidized polyethylene wax can effectively improve the demoulding effect in the later stage.
5. PVC products that require high-speed production, such as PVC high-speed extrusion edge banding. For lubricating formulas that require better metal stripping and anti-precipitation, oxidized polyethylene wax is a very suitable late lubricant.
6. PVC products that require surface finish, such as PVC injection molding pipes and fittings. Adding oxidized polyethylene wax can significantly improve the surface gloss of pipe fittings.
7. PVC products with complex cross-sections, such as special PVC profiles. Adding oxidized wax can better control plasticization and fluidity, and avoid precipitation.
8. PVC products with high filling content, such as SPC/WPC floors. Oxidized wax can better improve the plasticization speed under high calcium formulas, protect the screw, and extend the life of the screw.
9. PVC products that require electrical properties, such as PVC wire and cable materials. Adding oxidized wax can not only improve the surface gloss, but also effectively improve the electrical properties.
10. PVC products that need to be printed and pasted. For example, in PVC light boxes and advertising cloths, if only non-polar polyethylene wax is used as external lubricant, polar inks and adhesives may not adhere, resulting in unclear ink printing and loss of adhesive strength. Adding polar oxidized polyethylene wax can not only improve demoulding, but also increase the adhesion of inks and adhesives.
