Paper Grade refers to chemicals and additives specifically formulated for use in the pulp and paper manufacturing industry. These substances are designed to enhance paper quality, optimize production processes, and improve functional properties such as strength, brightness, smoothness, and resistance to water or aging. Common paper-grade chemicals include bleaching agents (like hydrogen peroxide or chlorine dioxide), fillers (such as calcium carbonate or kaolin), sizing agents (e.g., rosin or alkyl ketene dimer), and retention aids (like polyacrylamides) They may contain tailored additives to control pH, reduce foaming, or enhance dye adhesion. Environmental and safety regulations also apply, particularly for chemicals used in wastewater treatment or recycling processes. This grade is essential for producing everything from newsprint and packaging materials to high-quality specialty papers.

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.

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.

Titanium Dioxide

Titanium Dioxide (TiO₂) is a naturally occurring oxide of titanium known for its exceptional brightness and high refractive index. It is one of the most widely used white pigments in the world due to its excellent opacity, UV resistance, and chemical stability. Available in various crystalline forms—mainly rutile and anatase—it is used across numerous industries including paints, plastics, paper, cosmetics, and food. Industrial grades are often surface-treated to enhance performance in specific applications.
