Product description, Product introduction:

Used in the friction material Precipitated barium sulfate has good dispersibility, and strong precipitation resistance, it can be adsorbed easily with all kinds of resin, and can improve high temperature resistance and abrasion performance of resin binder and friction materials. The precipitated barium sulfate to adjust the performance of friction coefficient. The material is widely used in friction material industry.

The character of Fluorite:

The precipitated barium sulfate is made by chemical precipitation. In order to improve the dispersion, or other functional purposes,The so-called modified barium sulfate, is conducted on the basis of precipitated barium sulfate or barite surface modification treatment.There aren’t any difference in physical properties, chemical properties and usage. Of course, there may be detailed difference in usage because of different surface treatment agent, such as conductivity, PH value of acid or alkali, etc.
