Precipitated Barium Sulphate
Chemical synthesis used in the production of TLZ-PBS has endowed moreoutstanding performances. lt becomes a good filler that has a high whiteness.low oil absorption, low wear index, and low bulk color.
TLZ-PBS, acid and alkali resistance, good stability in water and organic mediumimproved its light resistance and weather resistance.
We use advanced grinding technology and professional crystal form control inthe production of TLZ-PBS, lts unique narrow particle size distribution, ultrafineparticle size, good specific surface area, and low viscosity, makes it suitable for

Synthesis Process：
By controlling the chemical reaction betweenbarium sulfide and sodium sulfate solutionsto produce barum sulfate in the originalparticle size.
diversified applications
The hardness value of TLZ-PBS can reach Mohs of 3,which endowed this product's low wear capacity.TLZ-PBS can keep the high light reflectivity not only inthe ultraviolet or infrared environment but also inbroad spectral range areas. This product can beapplied to any high gloss coating products, which canbring more business value to the customers.
Application Areas：Paints and coatings etc
