    Fumaric Acid CAS 110-17-8

    Fumaric Acid, chemically identified as trans-butenedioic acid (CAS 110-17-8), is a crystalline dicarboxylic acid that functions as a fundamental chemical intermediate in industrial polymerization and esterification processes. This organic compound, also technically referred to as (E)-butenedioic acid or allomaleic acid, serves as a structural building block in unsaturated polyester resin synthesis, imparting hardness and chemical resistance to the polymer matrix, and is frequently utilized in the production of alkyd resins and paper sizing agents. We provide bulk supply of this industrial material with competitive factory pricing to support large-scale manufacturing requirements. Our distribution framework ensures full compliance and technical transparency, making MSDS, TDS, COA available alongside customized specifications to match precise formulation parameters.

    FAQ - Technical & Supply Chain

    • Q:

      How is Fumaric Acid (CAS 110-17-8) chemically distinguished from Maleic Acid?

      A: Fumaric Acid is the trans-isomer of butenedioic acid, characterized by a higher melting point and lower solubility compared to Maleic Acid, which is the cis-isomer.
    • Q:

      What is the primary function of Fumaric Acid in resin formulations?

      A: In the manufacturing of unsaturated polyester resins and alkyd resins, Fumaric Acid is typically intended for use as a polybasic acid component to increase the glass transition temperature and improve the mechanical strength of the cured polymer.
