Oxidized polyethylene wax is an excellent new polar wax. Because the molecular chain of oxidized polyethylene wax has carbonyl and hydroxyl groups, its wettability and dispersibility in polar systems are better than polyethylene wax.

Also known as OPE wax. OPE wax has special properties such as low viscosity, high softening point, good hardness, good thermal stability, low high temperature volatility, good dispersion of fillers and pigments, excellent external lubricity, and It has strong internal lubrication and coupling effect, which can improve the production efficiency of plastic processing and reduce production costs. It has good compatibility with polyolefin resins, etc., and has good moisture resistance at room temperature and chemical resistance. Strong, excellent electrical properties, can improve the appearance of the finished product. It is an ideal product to replace montan wax, Sichuan wax, liquid paraffin, microcrystalline paraffin, natural paraffin, polyethylene wax, etc. It is made of polyethylene wax through a special oxidation process. , the molecular chain of oxidized polyethylene wax has functional groups.

1. Features

Oxidized polyethylene wax, also known as OPE wax,

OPE wax has special properties such as low viscosity, high softening point, good hardness, good thermal stability, low high temperature volatility, good dispersion of fillers and pigments, excellent external lubricity, and strong internal lubrication. It also has a 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. , 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.

2. OPE series wax production

It is made of polyethylene wax through a special oxidation process.

3. Scope of application

It is used as a dispersant, lubricant, brightener and 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.

For ink dispersant, anti-friction agent.

As a viscosity modifier for hot sols.

As aluminum foil composite paper processing aids.

Used as shoe polish, floor wax, glazing wax, car wax, cosmetics, match wax rod, ink wear-resistant agent, ceramics, precision casting agent, oil absorbing agent, sealant clay, Chinese medicine wax pill, hot melt adhesive, paint and powder coating matting agent, cable material additive, oil well wax absorber, crayon, carbon paper, wax paper, ink pad, photosensitive material matrix, textile softener, electronic component sealant, transistor encapsulant, rubber processing aid, automotive primer, dental material processing aid , steel rust inhibitor, etc.

4. The chemical composition of OPE wax:

Carbonyl-containing low molecular weight ethylene-vinyl acetate copolymer

Oxidized polyethylene wax has functional groups on its molecular chain, so its compatibility with polar resins is significantly improved, which is better than polyethylene wax.

(1) Chemical composition: low molecular weight oxidized polyethylene containing hydroxyl and carboxyl groups

(2) Properties: white and slightly yellowish powder, it is an excellent new polar wax in hard transparent and oxidized polyethylene wax. The compatibility of polar resins is significantly improved. The wettability and dispersibility in polar systems are better than that of polyethylene wax, and it also has coupling properties, and its performance is comparable to that of Honeywell A-C wax. White slightly yellow powder, with good chemical stability, soluble in aromatic hydrocarbons.

(3) Uses: It is widely used in water-based coatings and ink formulations to provide excellent abrasion resistance, anti-adhesion and anti-scratch properties. In the plastic processing industry, the internal and external lubrication of PVC is relatively balanced; adding oxidized polyethylene wax to the hard transparent and opaque PVC formulation 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.

5. Technical indicators:

The product is non-corrosive, has good chemical stability, and has good compatibility with rubber, plastic, paraffin and other materials. Appearance is light yellow powder,

Acid value: 7~26

Melting point ℃ 98-104

Density g/cm3 0.95

6. The difference between polyethylene wax (PE wax) and oxidized polyethylene wax

A. Different production

The general manufacturing methods of polyethylene wax include high pressure and low pressure polymerization. The wax obtained at high pressure has branched chains. Although the wax obtained at low melting point and low pressure is relatively hard in texture, it is slightly less slippery. Oxidized polyethylene wax It is obtained by oxidation of polyethylene wax.
Polyethylene wax and oxidized polyethylene wax manufacturer are mostly obtained by deep cracking and oxidation of high-pressure low-density polyethylene. Its molecular weight is 1000-3000, so it is also called low molecular weight polyethylene and low molecular weight oxidized polyethylene. The shape can be made into blocks according to needs. Form, flake and powder, the color is mostly white or light yellow

B. Performance difference

Polyethylene wax (PE wax), also known as polymer wax, is referred to as polyethylene wax. It is widely used because of its excellent cold resistance, heat resistance, chemical resistance and wear resistance. In normal production, this part of the wax can be directly added to the polyolefin processing as an additive, which can increase the optical translation and processing performance of the product. As a lubricant, it has stable chemical properties and good electrical properties.

The molecular chain of oxidized polyethylene wax has carbonyl and hydroxyl groups, and oxidized polyethylene wax is an excellent new polar wax factory, so the compatibility with fillers, pigments and polar resins is significantly improved, and its lubricity and dispersibility are better than those of polyethylene wax. Vinyl wax, but also coupling. Oxidized polyethylene wax has good compatibility with polyolefin resin, etc., good moisture resistance at room temperature, strong chemical resistance, excellent electrical properties, can improve the appearance of finished products, low viscosity, high softening point, good hardness and other special properties, good thermal stability, low volatility at high temperature, good dispersibility for fillers and pigments, excellent external lubricity, strong internal lubrication, and coupling effect, which can improve plastics. Processing production efficiency, reduce production costs.

At present, oxidized polyethylene wax is widely used in foam boards, and other products are less used due to price. It can significantly speed up plasticization and has good demoulding performance.
