Polyethylene wax refers to low molecular weight polyethylene with relative molecular weight less than 10000, usually with molecular weight ranging from 1000 to 8000. Pe wax has excellent properties and is widely used in ink, coating, rubber processing, paper, textile, cosmetics and other fields.

Polyethylene wax has good chemical stability, excellent mechanical properties, electrical properties, dispersibility, fluidity and demoulding. It has high softening point, low melting viscosity, high hardness and good wear resistance. As a dispersant of various masterbatches, a demoulding agent for polyolefin processing, a lubricant for polychloroethylene plastic processing, it is widely used in general plastic processing. Due to the introduction of polar groups, the physical properties of chemically modified polyethylene wax have been improved, so that the application field of pe wax has been extended to engineering plastics with higher performance requirements and rapid development momentum.
In the process of plastic processing, polyethylene wax can be used as dispersant of various masterbatches, processing lubricant of various plastics and compatibilizer of wood plastic composites. It is a common assistant in plastic processing industry.
Masterbatch dispersant
With the increasing development of the plastic industry, the plastic processing industry increasingly tends to use various functional masterbatches with convenient operation to reduce the cost of raw materials and process costs, improve production efficiency, and endow plastic products with different properties to meet the different needs of the market.
Plastic masterbatch mainly includes filling masterbatch, lubricating masterbatch, transparent masterbatch, pearlescent masterbatch, color masterbatch and antistatic masterbatch. The plastic masterbatch is prepared by adding more plastic additives than the conventional amount into the carrier resin. Therefore, the masterbatch can be directly added when forming plastic products.
Polyethylene wax can be used as dispersant of color masterbatch of various thermoplastic resins and lubricating dispersant of filling masterbatch and degradation masterbatch. Polyethylene wax has good compatibility with plastics, good heat resistance, good mixing and easy crushing, and does not affect the performance of terminal products; It can infiltrate, disperse and stabilize the particles of filler or pigment.

Plastic processing lubricant
The lubricant used in plastic processing is to improve the fluidity and demoulding of plastics, especially thermoplastics, during processing and molding. The main function of lubricant is to reduce the mutual friction between plastic materials and processing machinery and between plastic materials and internal molecules in the processing process, so as to improve the processing performance of plastics and improve the performance of products. The viscosity of polyethylene wax is much lower than that of plastic solution. It can be used as plastic melt index modifier. Because of its good thermal stability, low volatility at high temperature and good dispersion, it can improve the fluidity of plastic processing and improve the processing performance of plastic.
According to the action mechanism of lubricants in plastic processing and molding, lubricants are divided into internal lubricants and external lubricants. The internal lubricant has a certain affinity with the polymer, and its lubrication function is mainly to reduce the mutual friction between polymer molecules or reduce the force between polar polymer molecules. External lubricant mainly reduces the friction between polymer and processing machinery, which can improve long-term operability, dimensional stability, prevent scaling and increase production capacity. There are many kinds of lubricants. Most lubricants have both internal and external lubrication functions. The one with strong lubrication function is called external lubricant and the one with strong internal lubrication function is called internal lubricant.
Lubricants are widely used. Some lubricants are used in the processing of rigid PVC, polyolefin, polystyrene, ABS, phenolic resin, melamine resin, cellulose acetate, unsaturated polyester, polyamide and rubber. However, the main use of lubricant is still in hard PVC, so people often focus on hard PVC when evaluating the performance of lubricant.
PVC lubricant
PVC resin has excellent physical properties and can be made into rigid and flexible products. The process includes extrusion, coating, injection, blow molding, calendering, etc. Products include pipes, profiles, sheets, hollow products, wire and cable sheaths, etc. PVC resin has poor thermal stability, so it is necessary to add heat stabilizer and lubricant during processing. The lubricant can prevent the resin from staying in the extruder or causing resin decomposition due to local overheating, and make the resin easy to form. PVC plastic profiles are widely used as indoor decoration profiles, building water supply and drainage pipes and plastic steel doors and windows. Plastic profile is made of PVC and more than ten kinds of plastic additives by blending modification and extrusion, and lubricant is an important additive.

Polyethylene wax is mainly used for external lubrication and has strong external lubricity. It also has good lubricity in the middle and later stages of molding processing. It can be regarded as a lubricant in the middle and later stages. It is suitable for producing products with complex sections. It can be used in lead salt stabilization system, non-toxic calcium and zinc composite stabilization system and rare earth composite stabilization system. For example, SN9010W and SN9079W of Qingdao Sainuo have excellent lubricity. They are applied to various types of PVC processing processes, especially in PVC calendering and extrusion processes, which can significantly improve the plasticization of PVC and improve the mechanical strength of products; It is used for processing high-temperature hard materials and has outstanding anti viscosity and anti scorching properties. The oxidized wax powder is mainly used as an external lubricant for hard and soft PVC processing. It can improve torque, reduce the precipitation of organotin and lead salt stable system, have extremely high external lubrication and demoulding effect, and do not affect the Vicat thermal change temperature and impact strength of products.
