Guizhou Rich Mine Industrial Co., Ltd is professional manufacturer of micronized natural barium sulphate, located in Guizhou

Province famous by quality and abundant nature baryte ores. We are focusing on researching and utilizing of baryte ores.

Our company established the first class production foundation of micronized barium sulphate , introduced the most advanced

Alpine air jet mill and classifier from Germany, Atlas oil free screw compressor from Sweden. We adopted the ISO quality system.

Equipped with the high end testing and analytic instrument: Malvern and Photovolt to guarantee the accuracy and authenticity

of the size and scatter of our products, keeping supplying the quality products for the chemical industry around the world.

Product characteristics

QFR^® micronized barium sulfate has a good chemical inertness, which renders it a better compatibility and makes it easy to

organic composite with other materials and enhance the bonding; the suspension system is very stable and never produce

flocculation or precipitation.

The fine particles of QFR^® micronized barium sulfate completely remain the original crystalline structure of BaSO4 when the

average particle size (D50) is only 1.5 Mu. The specific surface area, surface atomic number and surface atomicity are enormous,

thus the hiding capability, the attraction, the dispersibility,the fluidity and optical prosperities have great changes, which absolutely

exceed the original fine properties of barium sulfate, and it becomes an outstanding pigment extender.

The fine particles of QFR^® micronized barium sulfate have a good scattering and hiding capability, and as a carrier of pigment, it

can make the pigment highly decentralized and provide an even color; high whiteness can make the coating clearer and purer;

special crystal structure and high refractive index can make the color rich and full.

The surface of QFR^® micronized barium sulfate can make the coating film bond with the substrate more strongly; uniform

submicron fine particles can make the coating film flatter and smoother and then more robust and durable.

The good chemical inertness, acid resistance, high temperature resistance and other special properties of QFR^® micronized

barium sulfate greatly improves the weather ability of coating.

Low oil absorption of QFR^® micronized barium sulfate can increase the critical volume concentration of coating and save more

resin base materials, so using QFR^® micronized barium sulfate is more economical and reasonable.
