Product Description

Maleic anhydride is an organic compound, occurring in a solid state. It is either colourless or white with an acrid odour and is the acid anhydride of maleic acid.

Usage:

  • Maleic anhydride is used in the production of unsaturated polyester resins (UPR) which in turn is used to make fibreglass reinforced plastics, used in a wide range of applications such as automobiles, tanks, pipes, bathroom fixtures, etc.
  • 1, 4-butandiol, BDO, a chemical made from crude maleic anhydride is used in the production of thermoplastic polyurethanes, elastane and spandex fibres, polybutylene terephthalate (PBT) resins, and a host of other products. It is one the fastest growing chemicals in the world.
  • Lubricating oil additives, synthesized from maleic anhydride, are used in gasoline and diesel engine crankcase oils as dispersants and corrosion inhibitors.
  • Maleic anhydride is also used in the food industry for artificial sweeteners and flavour enhancements.
  • Other products that use maleic acid in their production include hairsprays, adhesives and floor polishes.
  • It is also used insecticides, fungicides, detergents, pharmaceuticals and copolymers.
