Ultrafine barium sulfate

The ultra-fine barium sulfate products are used high-grade barium sulfate ore with production of current international advanced technology. Product with compact particles, narrow particle size dispersion, high chemical stability. Barium sulfate content of 98%, and its high whiteness, no black sports, no impurities, good dispersion, and has good wetting, excellent acid resistance, high temperature corrosion resistance. Can significantly improve the hardness and wear resistance products.

Features:

Narrow size distribution, with smaller amount of surface area and base materials, high gloss and liquidity available.High inert chemicals, acid and alkali, has a good sunscreen type and weather resistance.High purity and low impurities, no trace mineral and salt impurities( no corrosion or curing ingredients).Can improve product strength, wear resistance and geometric stability.Good compatibility with the matrix, combining close.Stable pigments, easily dispersed.
