Shanghai wax powder polyethylene wax characteristics and scope of application.
PE wax is polyethylene wax (PE-WAX), an ultra low molecular weight polyethylene. Polyethylene wax is generally divided into four types: oligomer wax, cracking wax, polymer wax and blending wax. Domestically produced is generally oligomer wax. Other cracking wax, polymer wax and blending wax are mainly produced in foreign countries. The performance of the theoretical analysis is better than the cracking 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 gloss and processability of the product. As a lubricant, it is chemically stable and has good electrical properties. Polyethylene wax has good compatibility with polyethylene, polypropylene, poly(vinyl acetate), 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. Polyethylene wax has a stronger internal lubrication effect than PVC and other external lubricants.
Main features: Low viscosity, high softening point, good hardness, non-toxic, good thermal stability, low temperature volatility, dispersibility of pigments, excellent external lubricity and strong internal Lubrication can improve the production efficiency of plastic processing. It has good moisture resistance at room temperature, strong chemical resistance and excellent electrical properties, which can improve the appearance of finished products.
Application range of polyethylene wax
1. Due to its excellent external lubrication and strong internal lubrication, it has good compatibility with polyethylene, polyvinyl chloride and polypropylene. It can be used as lubrication in extrusion, calendering and injection processing. Agent. It can improve the processing efficiency, prevent and overcome the adhesion of film, tube 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 concentrate masterbatch dispersant and filler masterbatch, degradation masterbatch lubrication dispersant, can improve the processing properties, surface gloss, lubricity and thermal stability of HDPE, PP and PVC.
3, used as a lubricant for cable insulation, can enhance the diffusion of fillers, increase extrusion rate, increase mold flow, and ease of demoulding.
4. As a rubber processing aid, it can enhance the diffusion of filler, increase the extrusion rate, increase the flow rate of the mold, and facilitate demolding.
5, light resistance and chemical properties, can be used as a carrier of pigments, can improve the wear resistance of paints and inks, improve the dispersibility of pigments and fillers, prevent pigments from sinking, and can be used as a flatner for paints and inks.
6, as a natural or synthetic fiber softener and lubricant, improve wear resistance, tear strength, anti-wrinkle and non-iron clothing sewing, reduce needle cutting and adjust the touch.
