Calcium Carbonate Uncoated is a naturally occurring mineral compound composed primarily of calcium, carbon, and oxygen with the chemical formula CaCO₃. It appears as a fine white powder or granules, widely used as a filler, pigment, and functional additive across various industries. The uncoated form means the calcium carbonate particles are not surface-treated, retaining their natural properties. It is valued for its high brightness, whiteness, and excellent compressibility. Uncoated calcium carbonate is used to enhance opacity, improve processing, and reduce costs in plastics, paints, coatings, adhesives, rubber, paper, and construction materials.

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.
Aluminum Fine Powder
Aluminum fine powder consists of finely divided aluminum particles, typically metallic and silvery-white in appearance. It is produced by atomization or grinding of bulk aluminum and is valued for its high surface area, excellent conductivity, and lightweight metallic properties. Aluminum fine powder is extensively used in various industrial applications including metallurgy, pyrotechnics, coatings, additive manufacturing, and as a pigment. Due to its reactivity, it requires careful handling and storage. Its fine particulate nature makes it particularly useful where rapid oxidation or reaction is desired, such as in explosives or energetic materials. It is also employed in the manufacturing of paints, inks, and cosmetics to impart metallic luster.
Calcium Carbonate Light
Calcium Carbonate Light is a finely ground, low bulk density natural mineral composed primarily of calcium carbonate (CaCO₃). Compared to standard grades, it has a lower density and larger particle size distribution, making it suitable for applications where light weight and high brightness are important.

Its chemical inertness and whiteness provide functional and aesthetic advantages across formulations.
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.
Corn Starch Industrial Grade
Corn Starch Industrial Grade is a finely milled, white powder derived from the endosperm of maize (Zea mays).
