SODIUM HYDROSULFITE Chemical compatibility with O-rings, rubbers, & plastics

Sodium Hydrosulfite is a white, crystalline inorganic compound with the chemical formula Na2S2O4. It is used in various industrial and chemical applications primarily as a reducing agent and bleaching agent. In the textile industry, Sodium Hydrosulfite is employed in the dyeing and printing of fabrics, providing effective reduction of dyes and improving colorfastness. It is also used in the paper and pulp industry for the bleaching of wood pulp and in the production of certain cosmetics and personal care products. In the chemical industry, Sodium Hydrosulfite is used as a reagent in the synthesis of various organic compounds and as a reducing agent in chemical reactions. Proper handling and storage of Sodium Hydrosulfite are essential to prevent moisture absorption and maintain its quality. It is generally considered safe for use, although proper safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are essential to prevent irritation and other health hazards. Its versatility and effectiveness make Sodium Hydrosulfite a valuable chemical in numerous applications.
