With the general nature of precipitated barium sulphate: high fineness and purity, good fluidity, surface treatment of the particle greatly improves the fluidity, dispersity and affinity with the application interface.
25kg/bag. Inner bag is plastic film bag, tied with rope; Outer bag is plastic woven bag or multi-layer paper bag, sewn by machine.
As special functional filler with modified treatment. It can be used for powder coatings, plastics, paints, inks, pigments, rubber, paper, batteries and other products with special requirements. It is especially effective when used for friction materials.
Avoid isolation and tear, kept in dry and ventilating place, avoid moisture and no mix with colorful matter.
