1250 mesh superfine precipitated barium sulphate

Short Description:

It is produced by domestic advanced chemical precipitation process, with superior physical properties, less mechanical impurities, extremely uniform fineness, amorphous white powder, non-toxic, insoluble in water, soluble in fuming sulfuric acid, slightly soluble in boiling The hydrochloric acid is chemically stable, and it is thermally reduced to barium sulfide with carbon. It will not change color when it encounters hydrogen sulfide or toxic gas in the air. It is a high-quality product of similar domestic products, giving the material high density and surface finish.

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.
