Maleic Anhydride

Maleic anhydride is an organic compound with the formula C₄H₂O₃. It is characterized as a white, crystalline solid with a sharp, irritating, acrid odor. It is a highly reactive chemical, primarily due to the presence of a reactive double bond (unsaturation) and two carbonyl groups arranged in a five-membered ring structure known as a cyclic dicarboxylic anhydride.

The main detailed uses of the product
  • Unsaturated Polyester Resins (UPR)
    Unsaturated Polyester Resins (UPR)

    Maleic Anhydride is primarily used to manufacture unsaturated polyester resins (UPR). These resins are essential for producing fiber-reinforced plastics, which are widely used in: Automotive parts (e.g., body panels, bumpers) Construction materials (e.g., pipes, tanks, building facades) Marine industry (e.g., boat hulls)

  • Specialty Chemicals & Derivatives
    Specialty Chemicals & Derivatives

    It acts as a precursor for high-value derivatives, including: 1,4-Butanediol (BDO), used in plastics, solvents, and elastomers. Tetrahydrofuran (THF), a solvent and precursor for spandex fibers. Fumaric and Malic Acids, employed as food additives (acidulants) and in pharmaceuticals

  • Agricultural Products
    Agricultural Products

    Maleic Anhydride is used to synthesize pesticides, herbicides, and plant growth regulators. Examples include malathion and other crop protection agents.

  •  Lubricants & Additives
    Lubricants & Additives

    It contributes to the production of lubricant additives (e.g., polyisobutylene succinimide), which enhance engine performance by reducing deposits and improving viscosity
