Talc is a hydrous magnesium silicate mineral with a chemical composition of Mg3Si4O10(OH)2. Talc is used as Industrial Raw Materials with other industrial raw material products such as Silica Flour, Limestone, Aggregate, Quicklime, Calcium Carbonate, Volcanic Rock and Abrasives. It’s characteristics are responsible for talc’s extreme softness, its greasy, soapy feel, and its value as a high-temperature lubricant. The platy shape of talc particles can increase the stiffness of products such as polypropylene, vinyl, polyethylene, nylon, and polyester. It can also increase the heat resistance of these products and reduce shrinkage. Where the plastic is extruded in the manufacturing process, it’s very low hardness produces less abrasion on equipment than harder mineral fillers.
It’s used in the manufacturing of ceramics products such as bathroom fixtures, ceramic tile, pottery, and dinnerware. Most paints are suspensions of mineral particles in a liquid. Most papers are made from a pulp of organic fibers. This pulp is made from wood, rags, and other organic materials. It’s is added to the asphaltic materials used to make roofing materials to improve their weather resistance. Ground talc is used as a lubricant in applications where high temperatures are involved. It is able to survive at temperatures where oil-based lubricants would be destroyed. Talc powder is used as a carrier for insecticides and fungicides. It can easily be blown through a nozzle and readily sticks to the leaves and stems of plants. Its softness reduces wear on application equipment.
Talc is used in many industries, including paper making, 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, etc. A major consumer of industrial minerals, the Ceramic Industry uses talc for “body” and glazing of wall tiles, sanitaryware. electrical insulating, and porcelain.
