Calcined Kaolin
$ 1.20
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 Carbonate Filler
Calcium Carbonate Filler is a high-quality, uncoated ground calcium carbonate (GCC) specially engineered for use as a filler in polyethylene (PE) and other polyolefin resins. This grade of calcium carbonate is designed to enhance the physical and mechanical properties of plastics while providing cost-effective bulk and improved processing. It is a fine, white, odorless powder with excellent brightness, high purity, and uniform particle size distribution. Its use improves stiffness, impact resistance, dimensional stability, and surface finish in polyethylene applications such as films, sheets, pipes, and molded parts.
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. This form is extensively used as a filler and extender in industries such as plastics, paints, rubber, paper, adhesives, and construction materials to improve opacity, brightness, and texture, while maintaining low weight and cost efficiency. Its chemical inertness and whiteness provide functional and aesthetic advantages across formulations.
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.
PP Raffia RH03( Wooven)
PP Raffia RH03( Wooven) is a woven polypropylene fabric made from homopolymer polypropylene resin, designed for high strength, durability, and excellent dimensional stability. It is widely used in the manufacturing of woven sacks, bags, and other flexible packaging solutions. The woven structure enhances tear resistance and load-bearing capacity, making it suitable for industrial and agricultural packaging applications.
Silicon Dioxide
Silicon Dioxide (SiO₂), commonly known as silica, is a naturally occurring inorganic compound found abundantly in the Earth’s crust. In its refined, powdered form, it is used as an anti-caking agent, filler, absorbent, and thickener across a wide range of industries. It is odorless, tasteless, chemically inert, and stable under normal conditions. Packaged in 10kg units, silicon dioxide is highly versatile and widely accepted for use in food, pharmaceutical, cosmetic, and industrial applications.
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.
Xysil Fumed Silica
Xysil Fumed Silica is a high-purity fumed silica produced through flame hydrolysis of silicon tetrachloride. It is an ultra-fine, amorphous, white powder with a very high surface area and low bulk density. Xysil 200 is widely used as a reinforcing filler, thickening agent, anti-caking agent, and rheology modifier in various industrial applications. Its unique physical properties improve the mechanical strength, viscosity, and stability of formulated products.
