MA is largely used in the production of unsaturated polyester resins. These resins are used primarily in fiber-reinforced plastics; materials with a wide and growing range of applications in boating, automobile and construction industries. It is also used as a co-monomer for unsaturated polyester resins, an ingredient in bonding agents used to manufacture plywood, a corrosion inhibitor, and a preservative in oils and fats.where maleic anhydride is used include the production of agricultural chemicals, malic acid, copolymers, fumaric acid, lubricant additives, surfactants and plasticizers. A lesser known use for MA is lubricating oil additives.
