GENERAL DESCRIPTION

Derived from Maleic anhydride. Fumaric acid's growth will remain below GDP growth. Its major applications in paper sizing and foods are stagnant. Demand will continue in applications that require Fumaric acid's specialized properties, but competition from lower-priced Maleic anhydride, Fumaric acid's precursor, will continue to limit growth in new applications.
