The function of oxidized polyethylene wax in PVC


Oxidized polyethylene wax molecular chain has a certain amount of carbonyl and hydroxyl groups, so the solubility with fillers, pigments, polar resin will be significantly improved. In polar system, wettability and dispersibility are better than those of polyethylene wax, and also have coupling property.

Ope wax has low viscosity, high softening point, good hardness and other properties, and itself non-toxic, good thermal stability, high-temperature volatility, it has a good dispersion for fillers and pigments. It has both excellent external lubrication and strong internal lubrication, as well as coupling effect, which can improve the production efficiency of plastic processing and reduce the production cost. It has good compatibility with polyolefin resin, etc. It has good moisture resistance at room temperature, strong chemical resistance, excellent electrical performance, and can improve the appearance of finished products. 

Use of oxidized polyethylene wax

In the plastic processing industry, the internal and external lubrication of PVC is more balanced. The lubricity of ope wax is superior to other lubricants when it is added to the rigid, transparent and opaque PVC formula. It is widely used in PE, PVC cable production, PVC profiles, pipe production, is an excellent new plastic processing lubricant. It can also be used in textile softener, car wax, leather softener making raw materials. 

Used as dispersant, lubricant, brightener and coupling agent for color masterbatch, polypropylene masterbatch, additive masterbatch and filling masterbatch and other pigments or fillers.

Used as lubricant for rubber and plastic processing, a demulsifier and a phase solvent, Eva Wax has a good miscibility with all kinds of rubber. Because of its high melting point and low viscosity, it promotes good resin fluidity, relatively reduces the power consumption of resin mixing, and reduces the adhesion between resin and mould, easy to get out of the film, plays the role of internal and external lubrication, and has a good anti-static. 

Used as a dispersant of ink, anti-rub agent;

Used as viscosity regulator of thermal sol;

Used as  shoe polish, floor wax, wax polish, car wax, cosmetics, matches wax rod, wear-resisting agent of printing ink, ceramics, precision casting, oil absorbent, sealing daub, Chinese medicine wax pill, hot melt adhesives, paint and coating flatting agent, cable feed additive, crayon, carbon paper, waxed paper, inkpad, photographic materials, textile softener, matrix electronics packet agent, rubber sealant, transistor

Rubber processing auxiliaries, automobile bottom oil, dental materials processing auxiliaries, iron and steel antirust agent, etc.

At present, oxidized polyethylene wax is used in a lot of foamed board, PVC foamed board is the most difficult PVC products to produce, is the most difficult to solve the most problems, the addition of oxidized polyethylene wax can significantly accelerate the plasticization, here we can see the uniqueness of oxidized polyethylene wax.
