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

Sodium Nitrate is a white, crystalline inorganic compound with the chemical formula NaNO3. It is used in various industrial, chemical, and agricultural applications as an oxidizing agent and fertilizer. In agriculture, Sodium Nitrate is employed as a nitrogen fertilizer, providing a readily available source of nitrogen for plants. It is also used in the production of explosives, where it acts as an oxidizing agent in the formulation of dynamite and other explosives. In the food industry, Sodium Nitrate is used as a preservative and curing agent for meats, helping to prevent spoilage and enhance flavor. Proper handling and storage of Sodium Nitrate are essential to maintain its quality and prevent moisture absorption. It is generally considered safe for use in regulated amounts, 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 Nitrate a valuable chemical in numerous applications.
