Talc Powder 325 Mesh Industrial

Talc Powder 325 Mesh Industrial (CAS 14807-96-6, molecular formula Mg3Si4O10(OH)2) is a raw material for tile, sanitaryware, tableware and refractory production, where particle size and impurity profile drive fired colour and body strength. China Chemicals supplies it at MgO 30% min in pack sizes from 1 kg through to 1000 kg Bulk Bag, so laboratory trial quantities and full production volumes can be sourced from the same specification.

It is also traded as Talcum, Steatite, Hydrated Magnesium Silicate. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.

Typical applications

Steatite and cordierite ceramic body formulation
Extender and anti-sag additive in paint
Reinforcing filler in polypropylene compounds
Anticaking and dusting agent in rubber processing
Paper coating and filler
