- Features and Benefits
The MicroTalc® is a magnesium silicate mineral with a monoclinic crystal structure. It is characterized by its softness and platy or lamellar physical structure. When ground into a fine powder, this lamellar property gives a smooth, soapy feel. Our MicroTalc® range offers very high dry brightness (whiteness) and acid resistance, heat stability, electrical resistance (dielectric strength), UV resistance and ease of dispersion in dry powder formulations.
Applications & Uses

- Uses
The main uses of MicroTalc® include:
- In the manufacture of personal care products (e.g. soaps).
- As an inert reinforcing filler in paints, coatings, sealants, mastics and grouts.
- As an opacifier and pigment extender in paints, plastics and paper.
- As a pitch (or stickies) absorbent in the production of paper pulp fiber.
- In coated paper manufacture (providing gloss, finishing and reinforcement).
- As a pelleting and extrusion aid in food & feed manufacture.
- As a bulking agent and dispersive diluent in pharmaceuticals.
- As the base ingredient in talcum powder blends.
- As a fire-resisting component in ceramic products.
- As a reinforcing constituent in rubber and waterproofing compounds.
- As a fluidising agent in fire extinguisher powders.
- In polishes and rubbing compounds.
- Promoting strength, heat and acid resistance in thermosetting polymers.
