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 exposure and tear, store in dry and ventilated warehouse, need a cushion layer to avoid moisture and don't store with colored materials.
Uses: Mainly used in powder coating and plastic industry. When it was used in coating, features include thin film, good glossiness and leveling property; When it was used in plastics, it can effectively improve the mechanical an optical property. It also can be used in paint, printing ink, pigment, rubber, paper, battery,and other industries.
