What Is The Role Of Oxidized Wax In PVC Products

What is the role of oxidized wax in PVC products? Oxidized wax has a wide range of applications in the processing of PVC products, as follows:
1. Transparent products: such as PVC transparent shrink film, adding polar oxidized wax can avoid affecting transparency and improve demolding performance.
2. Foamed products: such as PVC foamed sheets, the dynamic molding process has higher requirements for PVC plasticization and melt strength. By adding oxidized polyethylene wax, the quality of foaming is guaranteed and the surface finish is improved.

3. Especially thick products: such as ultra-thick PVC pipes, ultra-thick PVC products have higher requirements for plasticization, and oxidized polyethylene wax can effectively help plasticization.
4. Especially thin products: such as PVC decorative films, require higher PVC demolding performance. Oxidized polyethylene wax can better help the later demolding effect.
5. Products requiring high-speed extrusion: such as PVC high-speed extrusion edge banding, require better metal stripping and anti-precipitation. Oxidized polyethylene wax is a suitable late lubricant.
6. Products requiring surface finish: such as PVC injection molding pipe fittings.
7. Products with complex cross-sections: such as PVC profiles, adding oxidized wax can better control plasticization and fluidity and avoid precipitation.
8. Highly filled products: such as PVC floors, PVC stone plastic wallboards and other highly filled products, oxidized wax needs to be added in the actual processing of PVC products, and the higher the acid value of the oxidized wax, the more obvious the internal lubrication effect of the oxidized wax, and the faster the plasticization speed.

In addition, oxidized polyethylene wax is regarded as an excellent new plastic processing lubricant in the plastic processing industry. It is widely used in PE, PVC cable production, PVC profiles, and pipe production. It can also be used as a dispersant in masterbatch processing; auxiliary materials for asphalt modification and waterproofing coils; oscillation aid materials for road marking paints; viscosity regulators for hot melt adhesives; leather finishing agents, polishing wax, floor wax and other processing aids.
