What is the difference between PE wax and paraffin wax?

1. Different molecular structure

PE wax: is a low molecular weight polyethylene homopolymer or copolymer.

Paraffin wax: a mixture of hydrocarbons with a carbon number of about 18-30, the main component is linear alkanes (about 80%-95%), a small amount of alkanes have separate branches and long single-chain chains. Cyclocycloalkanes (the total content of the two is less than 20%).

According to the degree of refining, it can be divided into three types: fully refined paraffin, semi-refined paraffin and crude paraffin.

2. Different applications

PE wax: In normal production, as an additive, PE wax can be directly added to polyolefin processing, which can increase the optical translation and processing performance of the product. As a lubricant, it has stable chemical properties and good electrical properties. Polyethylene wax has good compatibility with polyethylene, polypropylene, polyvinyl wax, ethylene propylene rubber, and butyl rubber. It can improve the fluidity of polyethylene, polypropylene, ABS and the mold release of polymethyl methacrylate and polycarbonate.

Because of its excellent cold resistance, heat resistance, chemical resistance and abrasion resistance, it has been widely used. The main functions of polyethylene wax in solvent-based coatings are: matting, scratch resistance, abrasion resistance, polishing resistance, anti-marking, anti-blocking, anti-precipitation, and thixotropy;

Paraffin: Mainly used in the manufacture of matches, fiberboards, tarpaulins, etc. After adding polyolefin additives to paraffin wax, its melting point is increased, and adhesion and flexibility are improved. It is widely used in the production of moisture-proof and waterproof wrapping paper, cardboard, surface coating of certain textiles and candles.

3. Different features

PE wax: It is a chemical material. The color of polyethylene wax is small white beads/flakes. It is formed by an ethylene polymer rubber processing agent. It has a high melting point, high hardness and high gloss. The color is white and other characteristics.

Paraffin wax: Paraffin wax has high latent heat of phase change, almost no overcooling, low vapor pressure during melting, difficult chemical reaction, good chemical stability, after repeated heat absorption, the phase change temperature and latent heat of phase change change little and are released, self-nucleating , No phase separation and corrosiveness.
