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

Sodium Bisulfide, also known as sodium hydrosulfide (NaHS), is a yellowish crystalline compound used in various industrial and chemical applications. It is primarily employed in the paper and pulp industry for the production of kraft paper, where it acts as a reducing agent and helps in the pulping process. Sodium Bisulfide is also used in the leather industry for the dehairing of hides and skins, improving the efficiency and quality of leather production. In the mining industry, it is used as a flotation agent in the extraction of metals such as copper and molybdenum. Proper handling and storage of Sodium Bisulfide 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 Bisulfide. Its effectiveness as a reducing agent and flotation agent makes it a valuable chemical in various applications, although its use requires careful control to prevent hazards.
