MANGANESE DIOXIDE Chemical compatibility with O-rings, rubbers, & plastics

Manganese dioxide is a black or brownish-black crystalline solid with the chemical formula MnO₂, used in various industrial and chemical applications. It is primarily employed as a depolarizer in dry cell batteries, as a pigment in ceramics and glass, and as a catalyst in chemical reactions. Manganese dioxide is also used in the production of fertilizers and in laboratory research. Despite its utility, manganese dioxide can cause skin, eye, and respiratory irritation if not handled properly. Proper handling, storage, and safety measures, including the use of personal protective equipment, are essential to ensure safe usage and prevent exposure. Adequate ventilation and spill containment measures are also necessary.
