1. Oxidized polyethylene wax, also known as EVA wax, its characteristics
Because the EVA wax molecular chain contains a certain amount of carbonyl groups and hydroxyl groups, EVA wax is an excellent new polar wax , so the compatibility with fillers, pigments, and polar resins is significantly improved, and its lubricity and dispersion are better than polyethylene wax. It also has coupling properties. It is an upgraded product of PE wax, and its performance is the same as that of American Honeywell A-C waxes are equivalent. EVA wax has special properties such as low viscosity, high softening point, and good hardness. It is non-toxic, has good thermal stability, has low volatility at high temperatures, has excellent dispersion of fillers and pigments, and has excellent external lubrication. It has strong internal lubrication and coupling effects, 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. It has 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, oxidized polyethylene wax, etc.
2. EVA-ZL series wax production
They all use ideal recycled raw materials and are obtained through catalytic cracking. The cost and selling price are relatively low, unlike other products that add paraffin wax to reduce costs. and other substances. Please rest assured of the quality of this series of waxes.
3. Scope of application
Used as pigments such as concentrated color masterbatch, polypropylene masterbatch, additive masterbatch, filling masterbatch, etc. Dispersant, lubricant, brightener and coupling agent for fillers.
Used as lubricant, release agent and solvent for rubber and plastic processing. EVA wax has good compatibility with various rubbers. Due to its High melting point and low viscosity promote good fluidity of the resin, relatively reduce the power consumption of resin mixing, reduce the adhesion between the resin and the mold, easy to peel off, play the role of internal and external lubrication, and have good anti-static properties.
Used as a dispersant and anti-scuff agent for ink.
Used as a viscosity regulator for hot sol.
Used as a processing aid for aluminum foil composite paper.
Used as shoe polish, floor wax, glazing wax, car wax, cosmetics, match wax rods, ink wear-resistant agent, ceramics, precision casting agent, oil absorbent, sealing clay, traditional Chinese medicine wax pills, hot melt adhesive, paint and powder coating matting Agent, cable material additive, oil well wax absorbent, crayon, copy paper, wax paper, ink pad, photosensitive material matrix, textile softener, electronic component sealant, transistor encapsulating agent, rubber processing aid, automotive base oil, dental material processing aid , steel rust inhibitor, etc.
4. Chemical composition of EVA wax:
Low molecular weight ethylene-vinyl acetate polymer containing carbonyl group
Since oxidized polyethylene wax has a certain hydroxyl group on its molecular chain, its compatibility with polar resins has been significantly improved and is better than polyethylene wax. (1) Chemical composition: low molecular weight polyethylene containing hydroxyl and carboxyl groups ( 2) Properties: White slightly yellowish powder, with good chemical stability, soluble in aromatic hydrocarbons. (3) Usage: Balanced internal and external lubrication of PVC; in hard, transparent and opaque PVC formulas The lubricity of oxidized polyethylene wax added to it is better than other lubricants. It is widely used in PE, PVC cable production, PVC profiles, and pipe production. It is an excellent new plastic processing lubricant. It can also be used in textile softeners, car wax, Raw and auxiliary materials for making leather softener.
