Precipitated Calcium Carbonate
Precipitated Calcium Carbonate—also known as purified, refined or synthetic calcium carbonate. It has the same chemical formula as other types of calcium carbonate, such as limestone, marble and chalk: CaCO3.
The use of precipitated calcium carbonate fillers is the recommended choice in enhancing optical properties, durability, smoothness and ink adsorption in papermaking and improving the mechanical properties of plastic and rubber.
The addition of calcium carbonate to rubber increases tensile strength, abrasion resistance, and tear resistance even more than does vulcanization. Calcium carbonate is used in such small rubber products as oil seals and auto parts, and also in such large products as tires, tape, and rubber hoses.
China Clay
Kaolin (china clay) is a hydrated aluminum silicate crystalline mineral (kaolinite) formed over many millions of years by the hydrothermal decomposition of granite rocks.
China clay, soft white clay that is an essential ingredient in the manufacture of china and porcelain and is widely used in the making of paper, rubber, paint, and many other products.
Whiting Powder
The Whiting Powder is a very fine white powder slightly abrasive composed mostly of calcium carbonate. Whiting Powder can also be used to shine stainless steel, marble, glass, silverware, copper and many other non ferrous metals.
Whiting Powder is used as a filler pigment to increase the coverage of paints, coating and whitewash. It is also widely used in Rubber industries.
Talcum Powder
Talcum powder is made from talc, a mineral made up mainly of the elements magnesium, silicon, and oxygen. As a powder, it absorbs moisture well and helps cut down on friction, making it useful for keeping skin dry and helping to prevent rashes.
Talc is smooth and slippery. This is why, it is used as a lubricant. As such, it is used to dust moulds, apply between sheets of rubber or apply on surface of any rubber product to prevent stickiness.
Precipitated Silica
Precipitated silica is an amorphous form of silica (silicon dioxide, SiO2); it is a white, powdery material. Precipitated silica is produced by precipitation from a solution containing silicate salts.
Precipitated Silica is used as high-performance flatting agents, thickening agents and anti-corrosion pigments to improve the performance, workability and sustainability of rubber, coatings, paints, inks, adhesives, and sealants.
Barytes Powder
Barytes Powder, also called barite, is a mineral available worldwide, composed of barium sulfate (BaSO4). Barite is insoluble in water and is resistant to acid attack. The largest application of Barytes Powder is as a weighting agent in natural gas and oil field drilling muds.
Barite is used as a weighting filler in rubber to make “anti-sail” mudflaps for trucks. Barite is the primary ore of barium, which is used to make a wide variety of barium compounds. Some of these are used for x-ray shielding.
Some of its industrial end uses is as a weighting agent additive in cement, rubber and urethane foams. Barytes Powder is used in paint and powder coatings for metal protection and processing improvement. Barytes Powder is also used in friction products such as brake pads and clutch surfaces. Because barite is so dense that it reduces the passage of x-rays it is used in cement vessels for radioactive material containment, in gastrointestinal x-ray and in cathode ray masks in television sets and computer monitors. It also absorbs sound, so is included in sound-deadening sealants and underbody coatings in automobile and other vehicle manufacture.
Aluminum Silicate
Aluminium silicate is a name commonly applied to chemical compounds which are derived from aluminium oxide, Al₂O₃ and silicon dioxide, SiO₂ which may be anhydrous or hydrated, naturally occurring as minerals or synthetic.
It is currently found in the manufacture of pottery, bricks, cement, plastering material, color lakes (insoluble dyes), and insulators. As a raw material, it is commonly found in paper, plastics, cosmetics, and pharmaceuticals, and it is also used in pharmaceutical preparations as a filtering agent to clarify liquids.
Aluminium silicates are good reinforcing fillers and are used in all types of rubbers. They give comparatively harder vulcanizates than calcium silicates. They require a higher dosage of accelerators and would need booster additives like glycol or amine.
Calcium Silicate
Calcium silicate is an inorganic substance that is a hydrous or anhydrous substance with varying proportions of calcium as calcium oxide, and silicon as silicon dioxide.
Calcium silicate is used as an anticaking agent in food preparation, including table salt and as an antacid. It is approved as a safe food additive in a large variety of products.
It is often used together with carbon black to significantly improve the vulcanization properties and physical and mechanical properties of the latex product. … Generally, the tensile strength and elongation at break of NR reclaimed rubber reinforced with calcium silicate are three times that of carbon black.
Red Oxide Powder (Natural)
Red oxide powder is used by many industries. It is an inorganic compound which is available in India in great abundance at different regions. It is one of the most important minerals that is used in steel plant.
Red Oxide is a highly concentrated dry powder of the finest grade and is ideally suited for use in paints, rubber, paper, polishing rouge, ceramic, linoleum, wall paper, plastic asphalt, cement colours, mosaic tiles and flooring.
