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.
Binder
A binder is a broad category of substances—organic or inorganic—used to hold different materials together in a cohesive mass. Common binders include natural polymers (starch, cellulose derivatives, proteins), synthetic resins (PVA, acrylics, phenolics), and inorganic binders (clays, cement, lime). They are essential in industries such as pharmaceuticals, construction, coatings, ceramics, adhesives, and printing, where they provide structural integrity, adhesion, and controlled release properties.
Carbon Black
Carbon Black Concentrate Dispersions are homogeneous, ready-to-use formulations consisting of high-quality carbon black uniformly dispersed in a compatible liquid or solid carrier system. These products are engineered to deliver precise, repeatable carbon black loading levels at concentrations of 15%, 25%, 40%, and 50%, enabling manufacturers to achieve consistent jetness, tint strength, UV protection, electrical conductivity, and reinforcement across a wide range of industrial applications. Each variant is identified by a unique product code (169FF, 121FF, 13FF, 32PP) denoting the specific carbon black grade, with the percentage indicating the exact weight concentration of carbon black in the dispersion. These products eliminate the handling hazards, dust contamination, and dispersion inconsistencies associated with raw powdered carbon black, while significantly improving manufacturing efficiency, color matching, and end-product performance. They are designed to be "let down" (diluted) into a compatible base material at recommended ratios to achieve the target carbon black level for specific formulation requirements. These are industrial-grade products and are not intended for food, pharmaceutical, or cosmetic applications unless explicitly certified otherwise.
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.
Filler WTD
Filler WTD is a versatile, finely processed powdered filler primarily used in a wide range of industrial applications including paints, coatings, plastics, adhesives, sealants, rubber compounds, and construction materials. It is engineered to improve product performance by enhancing mechanical properties, increasing volume, reducing cost, and improving processing characteristics. Filler WTD typically exhibits excellent dispersibility, consistent particle size distribution, and good compatibility with various resin systems and binders. Its primary role is to act as an inert extender or reinforcing agent, providing bulk and stability while maintaining or enhancing the physical and chemical properties of the final formulation.
Kaolin
Kaolin is a naturally occurring, fine white clay mineral primarily composed of kaolinite. It features a soft, powdery texture and excellent absorbency. Kaolin is widely used across ceramics, paper, rubber, paint, and cosmetics industries due to its chemical inertness, whiteness, and plasticity. It acts as a filler, coating agent, and extender to enhance product quality and performance.
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.
