Pulping and bleaching chemicals play a critical role in transforming raw materials like wood chips or recycled paper into high-quality pulp. Alkaline agents such as caustic soda help break down lignin and separate cellulose fibers in the kraft process. Bleaching agents, including hydrogen peroxide and sodium chlorate, are used to whiten and purify pulp by removing residual lignin and color impurities. This stage enhances brightness, improves printability, and prepares the pulp for high-grade paper production.
