  • • Around 50% of world maleic anhydride (MA) output is used in the manufacture of unsaturated polyester resins (UPR). These resins are used primarily in fibre-reinforced plastics; materials with a wide and growing range of applications in boating, automobile and construction industries.
  • • Another significant use of maleic anhydride is in the manufacture of alkyd resins, which are in turn used in paints and coatings.
  • • Other applications where maleic anhydride is used include the production of agricultural chemicals, malic acid, copolymers, fumaric acid, lubricant additives, surfactants and plasticizers.
