Barium sulphate is a white crystalline powder. It is an important barium-containing mineral. It has strong chemical inertness, good stability, acid and alkali resistance, high density, moderate hardness, high specific gravity, high whiteness, and can absorb radiation (X-rays and Y-ray) and other advantages. It is used in a wide variety of industrial applications, including oil and gas drilling, as paint fillers and extenders, and in coatings, printing ink, rubber, papermaking, plastics, ceramics, etc.

Superfine barium sulphate is also used in high-grade marine paints, engineering plastics, powder coatings of household appliances, building materials, high-grade insulating rubber, lead acid battery, enamel glazed materials, etc.

Applying barium sulphate (about 25%) to PP makes the PP surface look like ABS without affecting the existing properties of PP, providing a high gloss and high hardness surface. The filling rate of Precipitated barium sulphate can reach 80% of total weight in formula. Precipitated barium sulphate can effectively isolate noise when it’s applied to drain pipes, loudspeaker box and sound equipment. It can also increase weight when it’s applied to curtains. Furthermore, when it’s applied to home appliance’s shell, it provides advantage like high gloss, nice color, scratch resistance, good dimensional stability and so on.
