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

Sodium Sulfide is a yellowish, crystalline inorganic compound with the chemical formula Na2S. It is used in various industrial and chemical applications primarily as a reducing agent and sulfur source. In the leather industry, Sodium Sulfide is employed in the dehairing of hides and skins, improving the efficiency and quality of leather production. It is also used in the paper and pulp industry for the production of kraft paper, where it acts as a reducing agent in the pulping process. In the chemical industry, Sodium Sulfide is used as a reagent in the synthesis of various organic compounds and as a flotation agent in the extraction of metals such as copper and molybdenum. Proper handling and storage of Sodium Sulfide are essential to prevent accidents and ensure safety, as it is highly toxic and can pose significant health risks if ingested or inhaled. Proper safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are essential when working with Sodium Sulfide. Its effectiveness as a reducing agent and sulfur source makes it a valuable chemical in various applications, although its use requires careful control to prevent hazards.
