Talc Products


What is Talc ?
Talc is the softest mineral (occupying place 1 in the Mohs hardness scale) known on our planet earth.
It is a hydrated magnesium silicate [Talc chemical formula is Mg3Si4O10(OH)2 ]. Also known as Steatite. It is the main
component of soapstone. Its crystals usually develop massive, leafy aggregates with laminar particles.
Synonyms of Talc includes soapstone, steatite, silicates, Talcum powder etc
Its silicate layers lie on top of one another without having a chemical bond but are bound to each other by weak Vander
Waals forces. This structure gives talc the platy appearance and its characteristic greasy or soapy feeling – hence the name
“soapstone”.

Talc properties :
Talc is lamellar, platy, organophilic, water repellent with special thermal and mechanical properties. It has a high capacity for
absorbing organic substances. It is also acid & alkali-resistant, chemically inert and non-toxic. Talc has neither aroma nor
taste. This makes it a very essential mineral in our day-to-day life.

Talc Industrial Applications & Uses :
Talc in Paper : Gives smoothness, brightness to paper & partially replaces TiO2. Also acts as pitch absorber, talc “clean” the
papermaking process by adsorbing any sticky resinous particles in the pulp onto their platy surfaces, thereby preventing the
agglomeration and deposit of these stickies on felts and calenders. As opposed to chemical pitch-control products that
pollute the process water, talc is removed together with the pulp, enabling the papermaker to operate more easily in closed-
circuit.
Talc in Paints :
Highly recommended for wood finishes, primers, putties, undercoats, architectural finishes, water based coatings. Its
laminar structure helps in better corrosion protection and also improves exterior durability of paints. Recommended for
exterior paints.
Talc for 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.
Talc in Foundries :
Used in mould making and for final finish.
Talc for Plastic & Rubber :
Used in variety of application as reinforcement filler.
Talc for Cosmetics :
Super fine talc powder is used in cosmetic for its smooth silky finish. Read More..
