Oxidized polyethylene wax, also known as OPE wax, is a bright plastic auxiliaries for internal and external lubrication. It is mainly produced by using polyethylene paraffin stearate stearic acid sulphate heated in a reaction vessel to a temperature of 380 °C for 6 to 8 hours.
The difference between oxidized polyethylene wax and polyethylene wax is that the oxidized polyethylene wax contains a modified wax product of a polar gene, so that the properties of oxidized polyethylene wax such as durability and polishing are much better than polyethylene wax. The chemical properties of oxidized polyethylene wax are more stable than polyethylene wax, non-toxic and non-corrosive, and make oxidized polyethylene wax more widely used.
Oxidized polyethylene wax application:
1. Good emulsifying property, because a large amount of oxygen-containing groups are introduced during oxidation of oxidized polyethylene wax, the interfacial tension during emulsification is lowered, so that a stable oxidized polyethylene wax emulsion can be obtained, and reduced the amount of the emulsification agent, which is very important for the polish.
2. Oxidized polyethylene wax has good compatibility with rubber, plastic, paraffin and other materials. The internal and external lubrication of PVC is relatively balanced, the addition of oxidized polyethylene wax to the rigid transparent PVC formulation is superior to other lubricants.
3. The molecular chain of oxidized polyethylene wax has a certain amount of carbonyl and hydroxyl groups. The oxidized polyethylene wax is an excellent new polar wax, so the compatibility with fillers, pigments and polar resins is significantly improved, lubricity and dispersibility. It is superior to polyethylene wax and also has coupling property.
4. Oxidized polyethylene wax has good compatibility with polyolefin resin, etc. It has good moisture resistance at normal temperature, strong chemical resistance, excellent electrical properties, improved appearance of finished products, low viscosity and high softening point. Good hardness and other special properties, non-toxic, good thermal stability, low volatility at high temperature, excellent dispersion of fillers and pigments, excellent external lubricity, strong internal lubrication, and even Together, it can improve the production efficiency of plastic processing and reduce production costs.
