White powder, relative density 4.0-4.5, insoluble in water, acid, alkali and other solvents, but soluble in strong acid and concentrated sulfuric acid. Heat resistance, acid resistance, alkali resistance, non-toxic, tasteless.




"YLFT" brand natural barium sulfate has strong chemical inertness, good stability, acid resistance, alkali resistance, water resistance, moderate hardness, high specific gravity, high whiteness, can absorb harmful rays of environmental protection materials. At the same time, it can also improve the rigidity, viscosity and wear resistance of the product. Make the product shiny and bright, good stability. Can replace part of the precipitated barium sulfate, titanium dioxide, active silica and other high-priced raw materials, reduce costs.



Widely used in various coatings, plastics, rubber, paint, ink and other industries. Can be used for acid-resistant rubber products and general products. Can also be used as a surface coating agent, sizing agent, weighting agent, also used in papermaking, ceramics, batteries, enamel, cosmetics and other fields. Also used in contact with food products.
