Talc Products

Talc Soapstone Mineral Company in India

Talc is the softest mineral (possessing place 1 in the Mohs' hardness scale) known on our planet earth. It is lamellar, platy, organophilic, water repellent with rare warm and mechanical properties. It has a high limit with regards to retaining natural substances. It is also acid & alkali-resistible, chemically inert, and non-toxic. Talc / Soapstone Powder Manufacturers In India has neither smell nor taste. This makes it an extremely essential mineral in our everyday life.

Its silicate layers lie on top of each other without having a chemical bond yet are bound to one another by weak Vander Waals forces. This design gives talc the platy appearance and its specialty greasy or soapy feeling – hence the name "soapstone”. Talc is a hydrated magnesium silicate [chemical formulation is Mg3Si4O10(OH)2 Otherwise called Steatite. It is the main Factor part of soapstone. Its crystals usually develop massive, bladed aggregates with laminar particles.

Industrial Applications

  • Paper : Gives smoothness, brightness to paper & partially replaces TiO2. Also acts as pitch absorber.
  • Paints : Highly recommended for wood finishes, primers, putties, undercoateds, architectural finishes, water based coatings. Its laminar structure helps in better corrosion protection and also improves exterior durability of paints. Recommended for expoxy and exterior paints.
  • Ceramics : Talc improves resistance to thermal shocks and gives superior electrical properties. It gives greater toughness to speak plugs and switch boards. It also improves dry pressing resistance of ceramic bodies.
  • Foundries : Used in mould making and for final finish.
  • Plastic & Rubber : Used in variety of application as filler.
  • Cosmetics : Super fine talc powder is used in cosmetic for its smooth silky finish.
