Aluminum hydroxide
Aluminum Hydroxide, chemically known as Al(OH)₃, is a white, odorless, and odorless powder or gelatinous substance. It is widely used in pharmaceuticals as an antacid to neutralize stomach acid and relieve indigestion and heartburn. Beyond healthcare, aluminum hydroxide is a crucial component in water purification, fire retardants, and as a precursor or filler in various industrial applications. It functions as a flame retardant by releasing water upon heating, thus cooling the material and diluting flammable gases. Due to its amphoteric nature, it can react both as an acid and base, enhancing its versatility. Aluminum hydroxide is often utilized in manufacturing aluminum salts and in producing aluminum oxide.
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 Heavy
Calcium Carbonate Heavy is a high-density, finely ground, natural mineral primarily composed of calcium carbonate (CaCO₃). Known for its higher bulk density compared to regular grades, this filler is widely used in applications requiring enhanced weight, opacity, and strength. It is commonly employed as a functional filler and extender in industries such as plastics, paints, coatings, adhesives, rubber, paper, and construction materials. Its inert nature, whiteness, and particle size distribution make it suitable for improving mechanical properties and surface finish, while also offering cost efficiency by replacing more expensive raw materials.
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.
Corn Starch Industrial Grade
Corn Starch Industrial Grade is a finely milled, white powder derived from the endosperm of maize (Zea mays). Unlike food-grade starch, industrial grade is tailored for non-food applications where its thickening, adhesive, and film-forming properties are exploited. It consists primarily of amylose and amylopectin polysaccharides and is valued for its biodegradability, renewability, and cost-effectiveness. Industrial corn starch is used extensively as a raw material or functional additive across a wide variety of manufacturing processes, including paper, textiles, adhesives, and packaging industries.
Magnesium Carbonate Light
Magnesium Carbonate Light is a fine, white, odorless powder primarily composed of magnesium carbonate (MgCO₃). It is characterized by its light texture and high purity. This mineral compound is widely used across various industries due to its excellent absorption properties, mild alkalinity, and non-toxic nature. Magnesium Carbonate Light is commonly employed as an antacid, drying agent, filler, and flow aid in food, pharmaceutical, cosmetic, and industrial applications.
Whiting
Whiting is a finely ground, white, chalky substance primarily composed of calcium carbonate (CaCO₃). It is widely used as a pigment, filler, and extender in various industrial and commercial applications. Whiting provides opacity, brightness, and smoothness to products, enhancing their appearance and physical properties. Its natural abundance and versatility make it an economical additive in multiple manufacturing processes.
