Talc Powder



Due to the platyness, softness, hydro-phobicity, organophilicity, inertness and mineralogical composition of Talc Powder that we are offering, they exhaustively provide specific functions in various industries. Our Talc Powder, which is produced by using harmless chemicals, has very little chemical reactivity and safe for usage. We are a noteworthy Talc Powder Manufacturer, Exporter and Supplier from Rajasthan (India). Before shipment, we our Talc Powder is tested on various parameters including mesh size, brightness, oil absorption and bulk density. Contact us for placing orders.

Talc is a hydrated magnesium sheet silicate with the chemical formula Mg3Si4O10(OH)2.

Talc is practically insoluble in water and in weak acids and alkalis. It is neither explosive nor flammable. Although it has very little chemical reactivity, talc does have a marked affinity for certain organic chemicals, i.e. it is organophilic. Above 900oC, talc progressively loses its hydroxyl groups and above 1050oC, it re-crystallizes into different forms of enstatite (anhydrous magnesium silicate). Talc's melting point is at 1500oC.

Talc's Properties
Platyness, Softness, Hydro-phobicity, Organophilicity, Inertness and Mineralogical Composition) provide specific functions in many industries.

Applications
  • Agriculture and Food
    Talc is an effective anti-caking agent, dispersing agent and die lubricant and therefore helps animal feed and fertilizer plants to function more efficiently. In premixes and agricultural chemicals, it makes an ideal inert carrier.Talc also is used as an anti-stick coating agent in a number of popular foods including chewing gum, boiled sweets, cured meats, and for rice polishing. In olive oil production, as a processing aid, it increases yield and improves the clarity of the oil.
  • Ceramics
    Talc is a phyllosilicate which imparts a wide range of functions to floor and wall tiles and sanitaryware, tableware, refractories and technical ceramics. In traditional building ceramics (tiles and sanitaryware), it is used essentially as a flux, enabling firing temperatures and cycles to be reduced.In refractory applications, chlorite-rich talc is transformed into cordierite to improve thermal shock resistance. For steatite ceramics, talcs with a microcrystalline are the most appropriate. During firing, the talc is transformed into enstatite, which possesses electro-insulating properties. As for very low iron content talcs, they are particularly suitable for use in frit, engobe and glaze compositions.
  • Paints & Coatings
    Talc confers a whole range of benefits to coatings. In interior and exterior decorative paints, they act as extenders to improve hiding power and titanium dioxide efficiency. Talc's lamellar platelets make paint easier to apply and improve cracking resistance and sagging. They also enhance matting. In anti-corrosion primers, talc is used to improve corrosion resistance and paint adhesion. Talc also brings benefits to inks, jointing compounds, putties and adhesives.
  • Paper
    Talc is used in both uncoated and coated rotogravure papers where it improves  printability as well as reducing surface friction, giving substantial improvements in productivity at the paper mill and print house. It also improves mattness and reduce ink scuff in offset papers. Used as pitch control agents, talc "cleans" the paper making process by adsorbing any sticky resinous particles in the pulp onto their platy surfaces, thereby preventing the agglomeration and deposition of these on the 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. In specialty papers such as colored papers or labels, talc helps to improve quality and productivity.
  • Pharma, Body Talc, Personal Care
    As it is soft to the touch and inert, talc has been valued for centuries as a body powder. Today it also plays an important role in many cosmetic products, providing the silkiness in blushes, powder compacts and eye shadows, the transparency of foundations and the sheen of beauty creams. In pharmaceuticals, talc is an ideal excipient, used as a glidant, lubricant and diluent. Soap manufacturers also use talc to enhance skin care performance.
  • Plastics
    Talc imparts a variety of benefits to polypropylene, for instance higher stiffness and improved dimensional stability. In automotive parts (under-the-hood, dashboard, bumper interiors and exterior trim), household appliances and white goods. It requires advanced milling technology to obtain the finest talc without diminishing the reinforcing power of its lamellar structure. Talc also is used for linear low density polyethylene (LLDPE) antiblocking and as a nucleating agent in semicrystalline polymers. In polypropylene food packaging applications, talc is a highly effective reinforcing filler.
  • Rubber
    Talc reduces the viscosity of rubber compounds, thereby facilitating the processing of moulded parts. It also improves extrudate qualities, increasing production rates and enhancing UV radiation resistance of exterior parts such as automotive profiles. In sealants and gaskets, they provide good compression resistance, while in pharmaceutical stoppers, they create a barrier against liquids. In cables, talc functions as insulators and in tire manufacture it makes excellent processing aids.
  • Waste water treatment
    Specialty talc can improve the performance of biological wastewater treatment plants. The talc particles ballast the flocs of bacteria and accelerate their sedimentation. The addition of talc results in top quality discharge and zero bacterial loss. It can help to upgrade plants without resorting to costly plant expansions. As opposed to most chemicals used to clean wastewater, such as chlorine or aluminium salts, talc is a natural, environmentally-friendly mineral additive. And because it is inert, it preserves the fertilizing value of sewage sludge.
