SULFUR DIOXIDE, DRY Chemical compatibility with O-rings, rubbers, & plastics

Dry sulfur dioxide is a colorless gas with a pungent odor, having the chemical formula SO2. It is used in various industrial and chemical applications primarily as a preservative, bleaching agent, and intermediate in the production of sulfuric acid. In the food industry, dry sulfur dioxide is employed as a preservative for dried fruits, wines, and other food products, preventing spoilage and maintaining freshness. It is also used in the pulp and paper industry for bleaching wood pulp and in water treatment processes for dechlorination. Proper handling and storage of dry sulfur dioxide are essential to prevent accidents and ensure safety, as it is highly toxic and can cause respiratory irritation and other health hazards. Safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are crucial when working with dry sulfur dioxide. Its versatility and effectiveness in various applications make dry sulfur dioxide a valuable chemical in numerous industries, although its use requires careful control to prevent hazards.
