Talc is widely used in many industries as a filler/extender and in other industrial applications due to its natural physical and chemical properties and relatively low price.
It is used in industrial applications because of its lamellar platy nature, softness, whiteness, hydrophobic features, atmosphere and acid resistance, high thermal strength, chemical inertness, high dielectric strength, high melting point and absorption features. Particle size distribution is a critical parameter in most talc applications.
Plastic industry consumes high quality ultra fine talc in automotive (bumpers, dashboards, interior trims etc.) and aesthetic (computer and TV bodies, garden furniture etc.) polypropylene, polyamides, cable PVCs and other plastic compounds. Talc is being increasingly used in HDPE, PP, LDPE, PVC, ABS & thermosetting compounds. It is excellent filler due to blending characteristics and thermal and electrical resistant. It is chemically inert. It provides the smooth feel to plastic surface. Due to its chemical inertness, superior electrical and thermal resistance and other properties talc imparts stiffness, hardness, tensile strength of plastic products, improves quality of their surfaces, gives them electrical, chemical and thermal resistance.
In paint industry talc is used in production of decorative paints, industrial coatings, pigment pastes, primers, enamels, adhesives, putties and other products of the industry. Due to natural properties and fine grinding of talc it improves fluidity and coverage properties of paint, imparts corrosion, acid, thermal, air resistance to them, increase smoothness and stability of paint products.
In paper industry talc is used in three stages of paper making - as a filler, to control pitch and stickies and in paper coating. During the paper making process, the micro impurities can clog the paper machinery. Talc being hydrophobic absorbs these micro droplets thus controlling their stickiness and avoiding clogging. High brightness of talc leads to reduction in usage of expensive whitening agents and helps in controlling gloss of the coat. Talc gives smoothness, yellow index, porosity, opacity to paper, improves its yellow index and reduces the deterioration of the machinery.
In ceramics talc is used mostly as a cheap filler in ceramic tiles, sanitary ware, dinnerware, porcelain and electrical insulating
In cosmetics talc is used as a body talc and as a filler in some cosmetic products - toothpaste, soap, detergents etc. Talc imparts stability, texture, water resistance and skin adhesion to cosmetics. In body talc it acts as a perfume carrier due to its chemical inertness lamellar structure.
In pharmaceuticals talc is used as a filler in tablets, ointments and dustings. Talc used in this industry must be highly pure, bacteria free, must contain no iron oxide, dolomite, carbon and other impurities.
Talc is used in production of many other products - in rubber and cable industries, in roofing, asphalt, in agricultural products, in food industry as a confectioneries filler and in candies and chewing gum coating, in sculpture, sealant and isolator production as a building material, in waste water treatment, in animal feed, in leather treatment, in shoe polish, welding rods, in cereal polishing, in pencils, glass fibre, synthetic diamonds and other products.
Talc produced by us is recommended in all the above industries, especially in those applications where particle size of talc is a major concern
