2022-03-17   Pageview:122

Oxidized polyethylene wax is an excellent new polar wax. Because the molecular chain of oxidized polyethylene wax has a certain amount of carbonyl and hydroxyl groups, its wettability and dispersibility in polar systems are better than that of polyethylene wax. Next, the Qingdao Sino polyethylene wax manufacturer will introduce you a superior oxidized polyethylene wax of Sino!

OPE wax has special properties such as low viscosity, high softening point, good hardness, non-toxicity, good thermal stability, low high temperature volatility, excellent dispersion of fillers and pigments, and excellent external Lubricity, strong internal lubricating effect, and coupling effect, can improve the production efficiency of plastic processing, reduce production costs, have good compatibility with polyolefin resins, etc., and have good moisture resistance at room temperature , Strong chemical resistance, 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., which is made of polyethylene wax through special oxidation. The oxidized polyethylene wax has certain functional groups on the molecular chain of the oxidized polyethylene wax.

Features

Oxidized polyethylene wax, also known as OPE wax, OPE wax has special properties such as low viscosity, high softening point, good hardness, non-toxicity, good thermal stability, low high temperature volatility, excellent dispersibility to fillers and pigments, both 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, 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.

OPE series wax production

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

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.

Chemical composition of OPE wax

Carbonyl-containing low molecular weight ethylene-vinyl acetate copolymer

Oxidized polyethylene wax has certain 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) Appearance: White with slightly yellowish powder particles. It is an excellent new polar wax in hard transparent and oxidized polyethylene wax. Because the molecular chain of oxidized polyethylene wax has a certain amount of carbonyl and hydroxyl groups, it is compatible with fillers and pigments. , The compatibility of polar resins has been 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 in the United States. 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.

Technical indicators

The product is non-toxic, 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

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 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. Ethylene, the shape can be made into blocks, flakes and powders according to needs, and 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 a certain amount of carbonyl and hydroxyl groups, and oxidized polyethylene wax is an excellent new polar wax, so the compatibility with fillers, pigments and polar resins is significantly improved, and the lubricity and dispersion are excellent. For polyethylene wax, it also has coupling properties. 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 It has special properties such as non-toxicity, good thermal stability, low volatility at high temperature, excellent dispersibility for fillers and pigments, excellent external lubricity, strong internal lubricating effect, and coupling effect. , which can improve the production efficiency of plastic processing and reduce production costs.

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