What is talc (soapstone)?

Talc is the world’s softest mineral. All talc ores are soft, platy, water repellent and chemically inert, but no two talcs are the same. Talc is a vital part of our everyday life. Talc is found in products such as magazines, car and house polymers, paints and tiles. Talc is a naturally layered hydrated magnesium sheet silicate that has a platelet structure with the chemical formula Mg3 Si4 O10 (OH)2.

Properties:

  • The softest mineral (Moh’s hardness 1)
  • Chemically inert, acid and alkali resistant

Application examples:

Paints and coatings: Construction systems, corrosion protection, grindable systems, adhesives;
improved viscosity and covering power, prevents sedimentation, fixes pigments.
Paper: Filler material, pitch control, surface coating; improves whiteness standards, cover properties and print ability.
Ceramics, rubber, asphalt: Filler material; increases rigidity and temperature resistance, reduces
processing temperatures.
Pharmacy and cosmetics: Powder, additive for pills; serves as a carrier for both dry and moist
materials.
Foods / animal feeds: Release agent and carrier substance for colors and nutrients (food additive),
flow regulating agent.
Sewage: Slurry coagulant, optimizing treatment effectiveness.
Other uses: Process additive, lubricant and anti-adhesive and many others.

Suitable Grades are:

  • Fine Talc
  • Super Fine Talc
  • Ultra Fine Talc
