The PE wax is a low molecular weight PE wax, which is a mixture of hydrocarbons having a molecular weight of about 2000 to 5000 and a paraffin wax having a carbon number of about 18 to 30. The main components are linear alkanes (about 80% ~ 95%), and a small amount of alkanes with single branches and monocyclic alkanes with long side chains (the total content of the two is less than 20%).

PE waxIt is a low molecular weight PE wax, which is a mixture of hydrocarbons with a molecular weight of about 2000 to 5000 and a paraffin wax with a carbon number of about 18 to 30. The main components are linear alkanes (about 80% ~ 95%), and a small amount of alkanes with single branches and monocyclic alkanes with long side chains (the total content of the two is less than 20%). Main characteristics of PE wax:

It has low viscosity, high softening point, good hardness, no du, good thermal stability, low high temperature volatility, excellent external lubrication and strong internal lubrication for pigment dispersion, which can improve the production efficiency of plastic processing, and has good room temperature humidity resistance, strong chemical resistance and excellent electrical properties, which can improve the appearance of the finished product.

Due to the excellent external lubricity and strong internal lubricity of PE wax, as well as good compatibility with PE wax, polyvinyl chloride, polypropylene and other resins, it can be used as a lubricant in extrusion, calendering and injection processing. It can improve processing efficiency, prevent and overcome the adhesion of films, tubes, and sheets, improve the smoothness and gloss of the finished product, and improve the appearance of the finished product.

PE wax can be used as a dispersant for concentrated masterbatch, filler masterbatch and degradation masterbatch of various thermoplastic resins, and can improve the processability, surface gloss, lubricity and thermal stability of HDPE, PP and PVC.

PE wax can be used as a lubricant for cable insulation materials, which can enhance the diffusion of fillers, increase the extrusion rate, increase the die flow rate, and facilitate demoulding.

The application of PE wax in rubber can improve the surface brightness and smoothness of the product after demoulding. In order to protect the rubber from electrostatic ozone and improve the dispersion of carbon black in the rubber, it is recommended to add 2-5 parts. PE wax is used as a chemical raw material in rubber, in which the color of PE wax is white beads/flakes, formed by polymer rubber processing aids. It has the characteristics of high melting point, high hardness, high gloss and white color.

The use of PE wax in rubber is a low molecular weight poly-homopolymer or copolymer widely used in coatings. By wax, it is meant that this polymer eventually floats in the surface coating in the form of microcrystalline wax, acting as a wax that is similar in appearance to paraffin, but with more different properties. The main functions of PE wax in different solvent-based coatings are: matting, scratch resistance, abrasion resistance, polishing resistance, scratch resistance, anti-blocking, sedimentation resistance, thixotropy, etc. Good lubricity and processability, metallic pigments.

1. Lubrication and dispersion: Generally, some fillers are added to the mixing of rubber or silica gel, as well as some carbon black, calcium carbonate, talc, etc. High transparency requirements will add some white carbon black and the like. The addition of PE wax can play a role in lubrication and dispersion.

2. Anti-sticking and demoulding: Generally, rubber is relatively sticky and easy to stick to the mold. PE wax plays a certain role in external lubrication.

3. Anti-ozone, the physical antioxidant of rubber products, migrates to the rubber products to form a protective film, which plays the role of anti-ozone.

4. Appropriate addition can reduce the Mooney viscosity of the rubber and play a plasticizing role, but note that excessive addition will affect the mechanical properties of the plastic.

5. The product has certain fluidity in the process of extrusion, calendering and sulfur molding.

6. Improve the homogeneity of the compound. The self-lubrication of the internal and external composite can disperse inorganic additives to a certain extent and improve the mixing uniformity of the composite.
