MALEIC ANHYDRIDE Chemical compatibility with O-rings, rubbers, & plastics

Maleic anhydride is a white crystalline solid with the chemical formula C₄H₂O₃, used in various industrial and chemical applications. It is primarily employed in the production of unsaturated polyester resins, as a co-monomer in polymer synthesis, and in the manufacture of agricultural chemicals. Maleic anhydride is also used as a curing agent for epoxy resins and as an intermediate in the production of fumaric acid. Despite its utility, maleic anhydride 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.
