Polyethylene wax and polyethylene have different degrees of polymerization, and their basic structures are the same. Commonly speaking polyethylene wax is polyethylene with smaller molecular weight, lower degree of polymerization and shorter molecular chain, because it has the nature of wax and can be used instead of paraffin wax, so it is called polyethylene wax.
How to make polyethylene wax? Production methods of polyethylene wax
1, Cracking method: high temperature and high pressure isolate air oxygen, using high temperature and high pressure make the large molecular weight of polyethylene resin long chain break, get small molecular weight of wax.
2, Polymerization method: through the production device, under the premise of adding special catalyst, appropriate high temperature and high pressure environment, generated, the process is the same as the polyethylene process.
3, Companion distillation method: production of polyethylene discharged residue, isolated oxygen high temperature and high pressure distillation, remove water, solvent, impurities and low molecular components, while cracking polymer residue, go of the middle and high molecular weight segment distribution of this part, this is the distillation method polyethylene wax.
4, Cracking method: high temperature and high pressure isolated air oxygen, the use of high temperature and high pressure makes the large molecular weight of polyethylene resin long chain break, get small molecular weight of wax.
5, Modified method: Europe and the United States polyethylene wax, represented by Germany, the United States is mainly modified grafting, so that it has a special functional group, in various plastics and other materials processing has a unique performance.
Polyethylene wax, also known as polymer wax or PE wax, has excellent cold resistance, heat resistance and chemical resistance. Normal production as an additive added directly to the polyolefin processing, can increase the gloss and processing performance of the product. As a lubricant, it has stable chemical properties and good electrical properties. It has low viscosity, high softening point, good hardness and other properties. It has good thermal stability, low volatility at high temperature, dispersion of pigments in masterbatch application, superior external lubricity and strong internal lubrication, which can improve the production efficiency of plastic processing.
