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

Maleic acid is a white crystalline solid with the chemical formula C₄H₄O₄, 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 as a pH adjuster in formulations. Maleic acid is also used in the food industry as an acidulant and in the manufacture of agricultural chemicals. Despite its utility, maleic acid 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.
