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.
