For practical applications, polyethylene wax is a good PVC lubricant and release agents, it is added in the rubber and plastics, could well enhance processing efficiency and improve product appearance gloss and abrasion resistance. Polyethylene wax used as lubricant can reduce mechanical contact between polymer and process, and harm of the conflict between the molecular chains. The former can be used as a lubricant, and the latter is PVC inner lubricant.
Polyethylene wax is an excellent lubricant because polyethylene, polypropylene and polyethylene wax are not fully compatible, so that it can performance as the external lubrication. Internal lubricant must be compatible with the polymer because usually the compatibility is small at room temperature, but compatibility will improve on the high temperature.
Polyethylene wax has a wide range of applications. It can be used in large injection molded products, not only improve the process mobility, but also can greatly advance exterior gloss and resistance to environmental stress cracking. Polyethylene wax can be used in inks, can promote conflict resistance, resistance to scratches, adhesion prevention, and can change ink rheology and improve hydrophilicity and print functions. Polyethylene wax be used in paint add texture effect. Polyethylene waxes for coatings are used as an additive, also used for film, contains promoted film lubrication, and improve scratch-resistant and waterproof.
