LUBRICANT FOR PVC-OXIDIZED POLYETHYLENE WAX
Oxidized polyethylene wax, also known as Ope Wax, is a new type of excellent polar wax. Because the molecular chain of oxidized polyethylene wax has some carbonyl and hydroxyl groups, its wettability and dispersibility in polar system are better than those of polyethylene wax.
Oxidized polyethylene wax, or OPE WAX,
ope Wax has special properties such as low viscosity, high softening point, good hardness, no toxicity, good thermal stability, low volatility at high temperature, excellent dispersibility for fillers and pigments, excellent external lubricity and strong internal lubricity It also has coupling effect, which can improve the production efficiency of plastic processing, reduce the production cost, has good compatibility with polyolefin resin, good moisture resistance at room temperature, strong chemical resistance, excellent electrical properties, and 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 and so on
2. Production of OPE SERIES WAXES
Made from polyethylene wax by a special oxidation process.
3. SCOPE OF APPLICATION
It is used as dispersant, lubricant, brightener and coupling agent for pigment or Filler such as concentrated masterbatch, polypropylene masterbatch, additive masterbatch, filling masterbatch, etc. .
As a 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.
As a dispersant of ink, anti-rub agent.
As a viscosity modifier for hot Sol.
As processing aids for aluminum foil compound paper.
For Shoe Polish, floor wax, Polish wax, car wax, cosmetics, match wax Rod, ink wear resistant agent, ceramics, precision casting agent, oil absorbent agent, sealant, Chinese medicine wax pill, hot melt adhesive, paint and powder coating matting agent, cable material additives, oil well wax absorbent, Crayon, carbon paper, wax paper, printing clay, photographic material Matrix, textile softener, electronic component sealant, transistor sealant, rubber processing AIDS, car bottom oil, dental materials processing AIDS, rust inhibitor and so on.
4. CHEMICAL COMPOSITION OF OPE WAX:
Low Molecular Weight ethylene-vinyl ACETATE COPOLYMER containing carbonyl group
There are some functional groups in the molecular chain of oxidized polyethylene wax, so the solubility of oxidized polyethylene wax with polar resin is improved obviously, which is better than polyethylene wax.
(I) chemical composition: low molecular weight oxidized polyethylene with hydroxyl and carboxyl groups
(2) properties: White slightly yellowish powder, in the hard transparent, oxidized polyethylene wax is an excellent new polar wax, because oxidized polyethylene wax molecular chain with a certain amount of carbonyl and hydroxyl groups, therefore, the compatibility with fillers, pigments and polar resins is significantly improved. In polar system, the wettability and dispersibility are better than polyethylene wax, and the coupling property is similar to that of American Honeywell A-C wax. White slightly yellow powder particles, with good chemical stability, can dissolve in aromatic hydrocarbons.
USES: widely used in waterborne coatings and ink formulations to provide excellent Abrasion Resistance, adhesion resistance and scratch resistance. In the plastic processing industry, the inner and Outer Lubrication of PVC is balanced, and the lubricity of oxidized polyethylene wax is better than other lubricants in the rigid transparent and opaque PVC formulation. It is widely used in PE, PVC cable production, PVC profile, pipe production, is a good new type of plastic processing lubricant. Also can be used for textile softener, car wax, leather softener production raw and auxiliary materials.
5. Technical indicators:
The product is non-toxic, non-corrosive, has good chemical stability, and rubber, plastic, paraffin and other materials have good compatibility. It has the appearance of light yellow powder, acid value: 7 ~ 26, Melting Point 98-104, density G / cm 30.95
6. Difference between polyethylene wax (PE wax) and oxidized polyethylene wax
A, different production
Polyethylene waxes are generally produced by high-pressure and low-pressure polymerization. Waxes obtained at high pressure have branched chains. Waxes obtained at low melting point and low pressure are relatively hard, but less slippery. Oxidized polyethylene wax is obtained by the oxidation of polyethylene wax.
Polyethylene wax and oxidized polyethylene wax are 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 block, flake and powder, the color is mostly white or light yellow
B, performance differences
Polyethylene Wax (Pe Wax) , also known as polymer wax polyethylene wax for short. Because of its excellent cold resistance, heat resistance, chemical resistance and wear resistance, it has been widely used. In normal production, this wax can be directly added to polyolefin processing as an additive, which can increase the product's photo-translation and processability. As a lubricant, it has stable chemical property and good electrical properties.
The oxidized polyethylene wax has a certain amount of carbonyl and hydroxyl groups in its molecular chain, and the oxidized polyethylene wax is an excellent new polar wax, so its solubility with fillers, pigments and polar resins is improved remarkably The lubricity and dispersibility are better than those of polyethylene wax, and also have coupling property. Oxidized polyethylene wax has good compatibility with polyolefin resin, good moisture resistance at room temperature, strong chemical resistance, excellent electrical properties, can improve the appearance of finished products, with low viscosity, high softening point, good hardness and other special properties Non-toxic, good thermal stability, low volatility at high temperature, excellent dispersion of fillers and pigments, excellent external lubrication, strong internal lubrication, and coupling effect, can improve the production efficiency of plastic processing Reduce the cost of production.
At present, oxidized polyethylene wax is widely used in foamed sheet, and other products are less used because of the price. The addition of oxidized polyethylene wax can obviously accelerate the plasticization and has good demoulding performance.
