Characteristics and application range of Shanghai wax powder polyethylene wax

Characteristics and application range of Shanghai wax powder polyethylene wax.

PE WAX is polyethylene wax (PE-WAX), an ultra-low molecular weight polyethylene. Polyethylene wax is generally divided into oligomer wax, cracked wax, polymeric wax and mixed wax four kinds, domestic production is generally oligomer wax, other cracked wax, polymeric wax and mixed wax is mainly produced abroad more, the performance of polymeric wax theoretical analysis is better than cracked wax, the specific use depends on the compatibility of the product. In normal production, this part of the wax can be directly added to the polyolefin processing as an additive, which can increase the luster and processing properties of the product. As a lubricant, it has stable chemical properties and good electrical properties. Polyethylene wax is soluble in polyethylene, polypropylene, polyvinyl cerate, ethylene-propylene rubber and butyl rubber. It can improve the fluidity of polyethylene, polypropylene and ABS and the release property of polymethyl methacrylate and polycarbonate. For PVC and other external lubricants, polyethylene wax has a stronger internal lubrication effect.

Main features: low viscosity, high softening point, good hardness and other properties, non-toxic, good thermal stability, low high temperature volatility, dispersion of pigments, both excellent external lubrication, and strong internal lubrication, can improve the production efficiency of plastic processing, good moisture resistance at room temperature, strong chemical resistance, excellent electrical properties, can improve the appearance of the finished product.

Scope of application of polyethylene wax

1. Due to its excellent external lubrication and strong internal lubrication, it can be used as a lubricant in extrusion, calender and injection processing because of its good compatibility with polyethylene, polyvinyl chloride, polypropylene and other resins. It can improve the processing efficiency, prevent and overcome the adhesion of film, pipe and sheet, improve the smoothness and gloss of the finished product, and improve the appearance of the finished product.

2, as a variety of thermoplastic resin concentrated masterbatch dispersant and filling masterbatch, degradation masterbatch lubricating dispersant, can improve the processing performance of HDPE, PP and PVC, surface gloss, lubricity and thermal stability.

3, used as a lubricant for cable insulation materials, which can enhance the diffusion of filler, improve the extrusion molding rate, increase the mold flow rate, and facilitate demoulding.

4. As a rubber processing aid, it can enhance the diffusion of filler, improve the extrusion molding rate, increase the mold flow rate, and facilitate demoulding.

5, good light and chemical properties, can be used as a pigment carrier, can improve the wear resistance of paint, ink, improve the dispersion of pigments and fillers, prevent pigment sinking, can be used as paint, ink polishing agent.

6, as a natural or synthetic fiber softener and lubricant, improve wear resistance, tear strength, wrinkle resistance and non-ironing clothing sewability, reduce needle cut and adjust the touch degree.
