HS CODE:3206421000
CAS No:1345-05-7
Molecular Formula:ZnS+BaSO4
Packing Detail:Packing in 25kg in net pp bag,26MT in the 20'' FCL
2. Description:
Lithopone B311¡ê¡§30%¡169; is a kind of lithopone whose hiding power is better than that of zinc oxide and worse than that of titanium dioxide.It has good heat-resisitance and is insoluble in water.
White powder, is a mixture of zinc sulfide and barium sulfate. Have high whiteness and good covering power. It is called Inorganic white pigment. Widely used as white pigment of plastics such as polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon and polyoxymethylene (POM), also for paint and ink . it is use to colourate for rubber products , linoleum, leather, paper, enamel.
3. Features:
1) A white pigment produced by precipitation through filtering,
heating and quenching works
2) Has mostly been replaced by titanium dioxide which is more
durable, but it is much cheaper
4. Application:
Mainly used of coatings, printing ink, rubber, plastic, powder, profiles, paint, paper, and leather, etc.
1) Used as a base for lake pigment
2) Used as a inert pigment for paint, ink and cosmetics
3) A large range of applications in plastic industry
4) Used as a filler in paper, leather, and linoleum
