What Is The Difference Between Different Melting Points Of PE Wax?

What is the difference between different melting points of PE wax? Polyethylene wax (PE wax), also known as high molecular wax, or polyethylene wax for short. It is widely used because of its excellent cold resistance, heat resistance, chemical resistance and wear resistance. In normal production, this part of wax can be directly added to polyolefin processing as an additive, which can increase the gloss and processing performance of the product.

Currently, most of the PE waxes on the domestic market are divided into several types:
1. Polyethylene is homopolymerized into PE wax. The PE wax produced by this method has good external lubrication performance, high gloss, narrow molecular weight distribution, and very stable quality. Representative products include the A-C series of the American Honeywell Company.

2. PE wax is a by-product of the polyethylene polymerization process, commonly known as secondary wax. It is purified through a refining process. This product has low viscosity, high melting point, good external lubrication performance, and low price, but the quality depends on the raw materials and process. There are certain fluctuations in the changes. Due to the characteristics of the refining process, there will inevitably be more low-melting point components in the product.

3. PVC thermally stable medium-low molecular weight polyethylene pyrolysis product, commonly known as pyrolysis wax. The pyrolysis process is simple and easy to operate, but the molecular weight distribution of the product fluctuates to a certain extent with the production process, and the quality is relatively low. Well, there will still be a small amount of low melting point components.

FT and PE wax can be used for PVC hard products to achieve super external lubricity, delay plasticization, and improve the gloss of the finished product; it is an excellent external lubricant to improve the brightness of the product, especially suitable for the extrusion process, which can significantly Increase the extrusion rate.
