1250 mesh superfine precipitated barium sulphate
Product Usage:
Widely used in paint coatings, water-based coatings, powder coatings, brake pads, plastics, rubber, chips, glass and other fields.
Printing-ink filler, can play the role of anti-aging, anti-exposure, increase adhesion, clear color, bright and non-fading.
Filler-tire rubber, insulating rubber, rubber sheet, tape, engineering plastics can enhance the anti-aging performance and weather resistance of the product, the product is not easy to age and become brittle, and can significantly improve the surface finish, reduce the production cost, as a powder coating The main filler is the main means to adjust the bulk density of the powder to increase the powder loading rate.
Functional materials-paper-making materials (mainly paste products), flame-retardant materials, anti-X-ray materials, battery cathode materials, etc. Both can show unique performance and are an indispensable and important part of related materials.
Other fields-ceramics, glass raw materials, special resin mold materials, special particle size distribution of precipitated barium sulfate and titanium dioxide compound, have a synergistic effect on the titanium dioxide, thereby reducing the amount of titanium dioxide.
