The papermaking industry is a complex ecosystem of chemical processes designed to transform raw fibers into versatile paper products. Within this landscape, Sodium Bisulfite (CAS 7631-90-5) plays a crucial, though often unsung, role. Its properties as a reducing and bleaching agent make it indispensable for ensuring the quality, brightness, and longevity of paper products. For professionals in the paper industry, understanding the applications and sourcing of this chemical is key to optimizing production.

One of the primary applications of Sodium Bisulfite in papermaking is its function as an 'antichlor'. After the bleaching process, which often uses chlorine-based chemicals to whiten wood pulp, residual chlorine can remain. This residual chlorine can degrade the cellulose fibers over time, leading to brittle paper and reduced product lifespan. Sodium Bisulfite effectively neutralizes these leftover chlorine compounds, preventing fiber damage and ensuring the durability of the final paper product. This makes it a vital chemical intermediate for paper quality.

Beyond its role as an antichlor, Sodium Bisulfite also contributes to the bleaching process itself. As a reducing bleach, it can help to break down lignin and other colored compounds within the wood pulp, contributing to a brighter and whiter paper. This dual functionality—acting both to aid in bleaching and to remove harmful residual bleaching agents—underscores its importance in achieving high-quality paper grades.
