SULFUR (MOLTEN) Chemical compatibility with O-rings, rubbers, & plastics

Molten sulfur is sulfur in its liquid state, used in various industrial and chemical applications primarily in the production of sulfuric acid, fertilizers, and vulcanized rubber. In its molten form, sulfur is also employed in the manufacturing of certain pharmaceuticals, pesticides, and explosives. Proper handling and storage of molten sulfur are essential to prevent accidents and ensure safety, as it is highly reactive and can ignite spontaneously upon contact with air. Safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are crucial when working with molten sulfur to prevent burns, inhalation hazards, and other health risks. Its versatility and effectiveness in various applications make molten sulfur a valuable element in numerous industries, although its use requires careful control to prevent hazards and ensure environmental and health safety.
