Polyethylene wax - the tool to solve the problem of PVC thermal stability is not good

Polyethylene wax product can improve the thermal stability of PVC and machining process of liquidity, increasing the extrusion efficiency of PVC products, improve the surface gloss of the product, and effectively reduce the separation phenomenon of PVC products processing process.

On the domestic market at present most of the PE wax is divided into several kinds:

1. Ethylene homopolymerization into PE wax, the production of PE wax lubricant performance is good, high gloss, narrow molecular weight distribution, quality is very stable, on behalf of the series of products such as the United States honeywell A - C.

2. The by-product in the process of ethylene polymerization, commonly known as the board wax, through the refining process, for purification of PE wax, the product of low viscosity, high melting point, the lubrication performance is excellent, price is low, but the quality has the certain fluctuation along with the change of raw material and process, due to the characteristics of the refining process, the product will have more components of low melting point.

3. The thermal stability of PVC low molecular weight polyethylene pyrolysis products, commonly known as wax cracking and the cracking process is simple easy to operate, but the molecular weight distribution of the product with the production process has the certain fluctuation, the quality is relatively good, there will be a small number of components of low melting point.
