SPECIFIED INFORMATION

In the cosmetic industry, excellent grade is used with high whiteness and other characteristics. Talc is used in personal care products such as soaps, handwashes, as well as beauty products including various facial creams.

Being an excellent excipient for tablets and carrier for medicated powders and a glidant and lubricant in tablet production, Talc is widely used for these purposes in the pharma industry. Talc acts as an excellent anti-tack agent in pharmaceutical coatings, thus ensuring flawless merchandise production. It is used in enteric coatings for targeted delivery of drugs.

Talc is used as a pigment, filler and extender in manufacturing house and industrial paints and primers, where it is used to improve optical and mechanical properties and production processes. It adds a large amount of benefits to color concentrates, inks, enamels, varnishes, putties, body fillers, mortars and asphalts. The talc used in manufacturing paints has some important properties like oil absorption, fineness of grind, color, resulting viscosity and chemical inertness. Talc is an important agent that helps to impart reinforce paint films control viscosity, integrity and prevent paint films sagging. Talc prevents settling of solid particles at the bottom of the container and improves paint's suspension. Since it is a very soft substance (1 on MOHS hardness scale), it causes only minimal abrasion to process and application equipment. It readily disperses in solvent-based as well as aqueous paints. High Quality Talc that has a surface area of greater then 12 m2/g is used in controlling gloss when an exact degree of Sheen or luster is required.

Paper industry is one of the major consumers of talc (especially Europe & Japan) as talc used as paper filler has a minimal negative effect on sheet strength but improves ink receptivity by a large margin. It also enhances opacity & brightness and reduces gloss. The reason why talc consumption is paper industry is growing is because of the availability of high quality talc. It has a distinct weight advantage of specific gravity of 2.8 vs. 4.2 for TiO2 when used as a Titanium dioxide extender in paper. This becomes extremely important as postal rates increase. Talc has the unique property of preferentially wetting oily substances in the presence of water which makes it extremely effective in pitch control. Pitch & other oleo resinous components of paper pulps cause serious manufacturing problems if not controlled. Talc when micronized to a surface area of 12m2/g or more, absorbs the pitch and helps in preventing accumulations that would otherwise deposit on the rolls, wire, and other parts of the paper machine. The talc products are used to pigment starch, latex, or alpha protein coating colors. Ultra fine talc products are also used with calcium carbonate, clay and titanium dioxide pigments to control rheological properties, gloss, calendaring, opacity, ink holdout & brightness. OMFILL exhibits the following characteristics.

Being one of the major consumers of the industrial minerals, the Ceramic industry uses Talc for variety of products. It uses talc for “body” and glazing of products such as Electrical Insulating (Steatite Talc), Sanitary Ware, Wall tiles, Porcelain Dinner Ware. Talc Suppliers provide talc used in this industry that is generally of 80 ~ 93% whiteness and 200 – 300 mesh. Enstatite is formed as talc disassociates during firing which produces high thermal expansion bodies, resulting in glazes being put into compression and thereby minimizes crazing. Low moisture expansion bodies are produced as a result, which results in good resistance to delayed crazing. Talc's massive nature helps in the process of dry pressing and in preparation of good casting slips. Because of the use of talc, low firing temperatures are possible. Over a wide temperature range the shrinkage and absorption properties of bodies are fairly constant. High quality white fire bodies are possible because of this. High-talc bodies can be readily fitted with glazes of unusual brilliance and attractiveness.

Talc is used as an important functional filler for manufacturing of compounded thermo-plastic and thermoset polymers. Because of its useful characteristics like platy particle shape & purity, it is used in plastic primarily as reinforcing filler. It helps increase the stiffness of polypropylene by 80% at a 20% loading and by 150% at a 40% loading. It also helps to reduce mold shrinkage, increase the heat resistance of polypropylene, reduce molding cycle time, and improve melt rheology. When compared to other reinforcing fillers, such as fiberglass and mica, talc is much less abrasive. It is used to give polypropylene superior low-temperature shock resistivity. Talc is used as an anti-block agent in polyethylene film, an additive that roughens the surface of tacky film to prevent it from adhering to itself. Loading levels can range from 0.5 to 1.0%. Talc is used in improving the hot strength of profile extrusions in vinyl and in reducing the shrinkage of floor tile. Fine particle size grades of high quality talc are used as nucleating agents for polyesters, nylon, semi-crystalline polyolefins, and chlorinated polyethylene. Talc can also be used in polyolefins at loading levels ranging from 1 to 50% by weight. Talc particles are a series of very small particles that are plate-shaped and they, when aligned, make possible a finished part with improved physical properties. Due to its nature the particle size & shape tends to produce slip or sort of lubricity. It's dispersion is somewhat difficult in conventional plastic mixing equipment due to its overall tendency for more bulking. Its sensitivity to pH changes is low; therefore, it can be used in applications where minor acidity is a problem. Talc, when used as filler in the manufacturing of plastics, has some unique applications. It is generally not used as the only filler in molding formulae but in combination with other filler materials. It helps in removal from molds, achieve a better shine or gloss on parts, and through its lubricating effect it lowers the extrusions die wear. It is also used as an effective anti-blocking agent. Talc promotes better fire retardancy and helps in processing and final application of mastics and various plastic sealants. Talc is also a useful substance when used as an aid in certain color applications, as a viscosity modifier to accomplish some improvement of overall finished product physical properties.
