The Different Types of Pulp and Paper Industry Chemicals

There are a wide variety of pulp and paper industry chemicals available. The most common types include:

• Bleaching chemicals are used to remove lignin and other impurities from pulp. The most common bleaching chemicals are chlorine, chlorine dioxide, and hydrogen peroxide.
• Coating chemicals are used to improve the surface properties of paper. The most common coating chemicals are starch, clay, and calcium carbonate.
• Fillers and extenders are used to increase the bulk and opacity of paper. The most common fillers and extenders are calcium carbonate, clay, and talc.
• Pigments are used to add color to paper. The most common pigments are titanium dioxide, carbon black, and iron oxide.
• Retention and drainage aids are used to improve the retention of fibers in the papermaking process. The most common retention and drainage aids are polyacrylamide and polyethylene oxide.
• Sizing chemicals are used to make paper resistant to water and other liquids. The most common sizing chemicals are rosin, starch, and alkyl ketene dimer.
• Strength additives are used to improve the strength of paper. The most common strength additives are polyacrylamide, polyethylene oxide, and guar gum.
• Wet-end chemicals are used to improve the performance of the papermaking process. The most common wet-end chemicals are dispersants, flocculants, and coagulants.
