Calcium Carbonate Uncoated
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.
Carbomer
Carbomer is a high molecular weight, crosslinked polyacrylic acid polymer used primarily as a rheology modifier, thickening agent, and suspension stabilizer. Supplied as a fluffy white powder, it exhibits high viscosity and excellent clarity when neutralized and dispersed in water or alcohol-water systems. Carbomer 940 is widely valued for its ability to form clear gels, control flow properties, and stabilize emulsions. It is commonly used in cosmetics, personal care, pharmaceuticals, and household formulations due to its consistency, compatibility, and efficient thickening performance at low concentrations.
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.
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.
Polywhite B
