Mazhar International not only obtains the Talc Lumps from their own mines operated in Abbotabad Region, Parachinar region and Afghanistan Region. Uses of Talc include different industries, paper, plastic, paint and coatings, rubber, food, electric cable, pharmaceuticals, cosmetics, and ceramics. A coarse grayish-green high-talc rock is soapstone or steatite, used for stoves, sinks electrical switchboards, crayons, soap, etc.
Pakistan is host to some of the best Talc deposits in the world, which are now being brought forth by Mazhar Minerals. With our own mines, each exhibiting a unique and diverse quality Mazhar Minerals have now made a systematic and well defined Mining Schedule and strategy to plan & sort out different grades of ores. Each ore sample is then carefully selected and analyzed on site, in terms of their Chemical & Physical properties.Since Pakistan has no open pit mines the very white talc has to be fetched from deep inside the mines and we place a lot of premium on our white products. Mazhar minerals mines are situated in the most beautiful & lush green valleys of the (KPK). Great care is taken at our mines to ensure that Child labour is not allowed and is totally forbidden.
Some of the important properties of Talc used in paint are colour, fineness of grind, oil absorption, chemical inertness and resulting viscosity. Talc helps to impart integrity, reinforce paint films control viscosity and prevent sagging of paint films. It improves suspension and prevents settling of solids at the bottom of the paint container. Because talc is very soft (1 on MOHS hardness scale), it causes only minimal abrasion to process and application equipment. It disperses readily in both aqueous and solvent-based paints. Talc having a surface area greater then 12 m2/g is used for gloss control when an exact degree of Sheen or luster is required. Omtalc has the ability to fulfill all major criterions for the paint industry. Our experts from Pakistan & abroad can assist you in delivering custom made talc for all your production needs. OMGLOSS exhibits following characteristics.
Talc is an important functional filler for compounded thermo-plastic and thermoset polymers. Because of its platy particle shape & purity is used in plastic primarily as reinforcing filler. It increases the stiffness of polypropylene by 80% at a 20% loading and by 150% at a 40% loading. It also increases the heat resistance of polypropylene, reduces mold shrinkage, improves melt rheology, and reduces molding cycle time. Compared to other reinforcing fillers, such as fiberglass, mica, talc is much less abrasive. It gives polypropylene superior low-temperature shock resistivity. In polyethylene film talc is used as an anti-block agent, an additive that roughens the surface of tacky film to prevent it from adhering to itself. Loading levels range from 0.5 to 1.0%. In vinyl talc is used to improve the hot strength of profile extrusions and to reduce the shrinkage of floor tile. Fine particle size grades are used as nucleating agents for semi-crystalline polyolefins, nylon, polyesters, and chlorinated polyethylene. Talc can be used in polyolefins at loading levels ranging from 1 to 50% by weight. Talc particles may be described as a series of very small plate-shaped particles which, when aligned, tend to make possible a finished part with improved physical properties. The nature of the particle size & shape will tend to produce slip or a form of lubricity. It is some what difficult to disperse in conventional plastic mixing equipment due to overall tendency for more bulking. The material is less sensitive to pH changes; therefore, it can be used in applications where minor acidity is a problem. Talc, as filler for plastics, has some special applications. Generally, it is used not as the sole filler in molding formulae but in combination with other filler materials. It facilitates removal from molds, helps achieve a better sheen or gloss on parts, and lowers the extrusions die wear through its lubricating effect. It is also an effective anti-blocking agent. Talc promotes better fire retardancy and aids in processing and final application of various plastic sealants and mastics. It is also useful as an aid in certain color applications, as filler for parts in contact with acids, and as a viscosity modifier to accomplish some improvement of overall finished product physical properties.

TALC has been in very great demand by the Pharma industry due to its purity, thermal and chemical inertness. Multinational companies like Roche, Glaxo Smith Kline, and Merck Marker have been using our talc since it was introduced.
Textile sizings are made up of a binder, starch, glue, or synthetic polymer together with mineral powders referred to as weight-adding agents. Finishing agents are employed to improve web impregnation, appearance, dye receptivity, to provide temporary sizing, and to add weight.
