The role of oxidized polyethylene wax in PVC

2022-03-01   Pageview:353

The molecular chain of oxidized polyethylene wax has a certain amount of carbonyl and hydroxyl groups, so the compatibility with fillers, pigments and polar resins will be significantly improved. The wettability and dispersibility in polar systems are better than that of polyethylene wax, and it also has coupling properties.

Oxidized polyethylene wax has the properties of low viscosity, high softening point, good hardness, and itself is non-toxic, good thermal stability, low volatility at high temperature, and excellent dispersibility to fillers and pigments. It has excellent external lubricity, strong internal lubricating effect, and coupling effect, which can improve the production efficiency of plastic processing, reduce production costs, and have good compatibility with polyolefin resins. It has good moisture resistance at room temperature, strong chemical resistance, and excellent electrical properties, which can improve the appearance of finished products. It is an ideal product to replace montan wax, Sichuan wax, liquid paraffin, microcrystalline paraffin, natural paraffin, polyethylene wax, etc. .

What is the role of oxidized polyethylene wax in PVC?

In the plastics processing industry, the internal and external lubrication of PVC is relatively balanced. Adding oxidized polyethylene wax to hard transparent and opaque PVC formulations has better lubricity than other lubricants. It is widely used in the production of PE and PVC cables, PVC profiles and pipes, and is an excellent new plastic processing lubricant. It can also be used as raw and auxiliary materials for textile softener, car wax and leather softener.

Used as dispersant, lubricant, brightener, coupling agent for pigments or fillers such as concentrated color masterbatch, polypropylene masterbatch, additive masterbatch, filler masterbatch, etc.

As a rubber and plastic processing lubricant, release agent and phase solvent, EVA wax has good compatibility with various rubbers. Due to its high melting point and low viscosity, it promotes good resin fluidity, relatively reduces the power consumption of resin mixing, and reduces resin and resin. The adhesion of the mold is easy to release the film, which plays the role of internal and external lubrication, and has good anti-static properties.

Used as dispersant and anti-friction agent for ink;

As a viscosity modifier for hot melt adhesives;

Used as processing aid for aluminum foil composite paper.
