Product name: Refined precipitated barium sulphate (BaSO4)
Properties: With the general nature of precipitated barium sulphate: high fineness and purity, less bulk density, surface treatment of the particle greatly improve the dispersity and affinity with the application interface.
Packaging: 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.
Cautions: Avoid isolation and tear, kept in dry and ventilating place, avoid moisture and no mix with colorful matter.
Uses: Mainly used in powder coating and plastic industry. When it used in coatings, features include thin film, good glossiness and levelling property; When it used in plastics, it can effectively improve the mechanical and optical property. It also can be used in paint, printing ink, pigment, rubber, paper industry, battery and other industries.
