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.

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.
