Product Description:
Main composition of talcum powder is hydrated magnesium silicate.
Usually it's made after crushing, treated with hydrochloric acid, water washing and drying.
Talcum powder features properties of lubricity, fire resistance, acid resistance, insulation, high melting point, strong adsorption force and other excellent physical and chemical properties, under normal circumstances it is stable, no obvious side effects.
Main indexes:
In the coating industry, talcum powder as the filler plays a role of skeleton, reduce manufacturing cost and improve hardness of the coating film.
In plastic industry, inorganic fillers play an important role in the plastic modification, become a indispensable modified additives. The addition of talc powder can change a variety of performance of plastic.
In paper industry, it nominantly has good features: to improve filler retention and improve paper smoothness; keep the properties of stability.
Used as additives for food industry and pharmaceutical industry.
We normally list 24 months as the shelf life in our COA, the real shelf life can be slightly longer than 24 months if it's stocked in good condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials), but it's still suggested to avoid long time storage.
