characteristic:

This product is an ester product with excellent thermal stability. The results of thermogravimetric analysis show that it does not decompose slowly until 400 ℃, with very little volatility. It is widely used as a lubricant in the processing of various engineering plastics. It can prevent the melt of plastic from adhering to the mold and equipment, and at the same time can make the product be demolded smoothly at high temperature. Even in the complex structure of the mold, it can ensure a good demolding. In addition, it can prevent the raw material during the feeding process. Melting in the area (bridging phenomenon). It is beneficial to increase the filling speed of the injection molding feed, so that the product can obtain a smooth surface and high finish. It has an excellent nucleation effect on partially crystallized plastics and can be used for transparent products.

use:
