Aluminium Silicate
Aluminium silicate is an inorganic compound composed of aluminum, silicon, and oxygen, often found naturally as a major component of clay minerals such as kaolinite, halloysite, and other aluminosilicates. It is a white to off-white powder with excellent thermal stability, chemical inertness, and physical durability. Due to its wide range of physicochemical properties—including high melting point, non-toxicity, and adsorptive capabilities—aluminium silicate is extensively used across diverse industries including ceramics, paints, paper, rubber, plastics, cosmetics, and pharmaceuticals. Its unique structure imparts benefits such as heat resistance, improved mechanical strength, and anti-caking properties, making it a vital raw material in both industrial and consumer products.
Calcined Kaolin
Calcined Kaolin is a fine, white to off-white powder produced by heating natural kaolin clay to high temperatures (typically between 600°C and 900°C) in a controlled process called calcination. This thermal treatment removes chemically bound water, changes the crystalline structure, and enhances the physical and chemical properties of kaolin. The resulting product exhibits increased brightness, hardness, and opacity, making it highly valuable as a functional additive and filler in numerous industrial applications. Calcined Kaolin is widely used in coatings, ceramics, plastics, rubber, paper, and paint industries to improve durability, brightness, and performance.
Calcium Sulphate
Calcium Sulphate is an inorganic compound composed of calcium, sulfur, and oxygen, commonly found in two forms: dihydrate (gypsum, CaSO4·2H2O) and anhydrous (CaSO4). It appears as a white or off-white crystalline powder or granules with low solubility in water. Calcium Sulphate is widely used in construction, agriculture, pharmaceuticals, food industry, and various industrial applications. It acts as a filler, hardening agent, and drying agent due to its physical and chemical properties. The dihydrate form (gypsum) is notable for use in plaster and cement, while the anhydrous form is often used as a drying agent and in refractory materials.
Coated Calcium Carbonate
Coated Calcium Carbonate is a fine, white, odorless powder consisting of naturally occurring ground calcium carbonate (CaCO₃) treated with a surface coating—typically stearic acid or other fatty acids—to enhance compatibility with non-polar matrices. This coating improves dispersion in plastic and rubber formulations, reduces moisture pickup, and enhances the physical properties of the final product. Compared to uncoated grades, coated calcium carbonate offers better hydrophobicity, improved flow properties, and stronger interfacial bonding in polymeric systems. It is widely used in plastics, rubber, paints, sealants, adhesives, paper, and more.
Master Fibre
Master Fibre is a high-quality synthetic fiber additive designed to reinforce concrete and mortar mixtures. It improves structural integrity by enhancing tensile strength, reducing cracking, and increasing durability. The fibers disperse uniformly within the mix, providing better load distribution and impact resistance in industrial, commercial, and residential construction applications. Master Fibre enhances performance without compromising workability, making it ideal for use in concrete slabs, pavements, beams, and repair mortars.
Polymer Fiber
Polymer Fiber refers to a wide range of synthetic fibers made from polymer materials such as polypropylene, polyester, nylon, polyethylene, and acrylics. These fibers are engineered for high tensile strength, durability, flexibility, and resistance to chemicals and moisture. Polymer fibers are widely used in construction, textiles, filtration, composites, and industrial applications to improve mechanical properties, enhance structural integrity, and provide specialized functional benefits.
Polywhite B
Polywhite B Chinaclay, commonly known as Chinaclay, is a naturally occurring, fine white clay mineral primarily composed of kaolinite. It is highly valued for its purity, whiteness, and fine particle size, making it suitable for a variety of industrial applications. Polywhite B improves texture, opacity, and durability in products and is widely used in ceramics, paper, paints, and rubber industries.
Sodium Sulphate
Sodium Sulphate (Na₂SO₄) is a white crystalline powder or granule, odorless and highly soluble in water. This 25kg packaged product is widely used in detergents, glass manufacturing, chemical industries, and pulp and paper processing. It acts as a filler, bulking agent, and drying agent, with excellent stability and non-reactivity under standard storage conditions. Its cost-effectiveness and availability make it an essential raw material in many industrial processes.
