Description

Barium Sulfate Precipitated is white powder or ointment made by chemic sedimentation method, which has an advantage in physical capability, less mechanical impurity and symmetrical granularity. It has high density and good filling ability, It is the upper product that compares with the same kinds in quality in the state. It has good dispersion, highly whiteness, excellent light fastness, and acid-resistant. It has an outstanding fire retardant, electric insulation, chemical inertness and middle surface area. Make it as functional filler and pigment which has good dispersive and affinity with other media. It could absorb X-radial and Y-radial and endow material with high density and the luster of surface.

APPLICATION:

-Paint & coating

It can be applied into paint & coating to control the painting’s viscosity, brighten the colors, improve the stability and enhance the impacting strength of coating products.

-Fillers

To be used in rubber tires, rubber, plastic sheet, tape, engineering plastics products for enhancing product’s anti-aging performance, can also significantly improve surface smoothness and products’ hardness to reduce production cost.

-Functional materials

To be used in papermaking materials (mainly for paste products), flame-retardant materials, X-defense materials, battery cathode materials. It’s an indispensable and important component of concerned materials which able to demonstrate the unique properties.

-Other field

To be used in porcelain, material for glass, special resin, taken place the Titanium Dioxide as the white pigment.
