Product Application
Product Overview & Classified Industrial Applications
General Product Description
Fumaric acid is a high-value essential organic chemical raw material and fine chemical intermediate, mainly produced through isomerization of maleic anhydride. Featuring stable trans molecular structure, non-toxic property and excellent thermal resistance, this compound covers multi-scenario application in food processing, coating manufacturing, synthetic resin, plasticizer production, pharmaceutical synthesis and textile printing industries.
1 Food & Beverage Industry (Integrated duplicate food usage from original Paragraph 2 & 3)
It acts as a premium long-lasting food acidulant (E297 food additive) widely applied in carbonated soft drinks, fruit wine, chilled beverages, concentrated fruit juices, canned fruits, pickled vegetables, ice cream and confectionery products, and it is often blended with citric acid to balance flavor and extend shelf life.
- It serves as the core acidic component for effervescent agents of solid drinks, producing uniform, stable foam and delicate mouthfeel;
- Its monosodium derivative, monosodium fumarate, is used as a natural sour seasoning for food processing.
2 Resin, Coating & Plastic Manufacturing Sector
- Primary raw material for synthesizing unsaturated polyester resins with outstanding chemical corrosion resistance and high thermal stability;
- Copolymerized with vinyl acetate to produce high-strength industrial adhesives; copolymerized with styrene for manufacturing fiberglass composite substrates;
- Non-toxic fumaric acid plasticizers are specially developed for vinyl acetate latex products that directly contact food materials.
3 Pharmaceutical & Fine Chemical Production
It functions as a key synthetic intermediate for pharmaceutical APIs and optical brighteners.
Specific chemical synthesis route: Fumaric acid reacts with sodium carbonate to generate sodium fumarate; sodium fumarate further reacts with ferrous sulfate to produce ferrous fumarate, a mainstream oral iron supplement clinically used for treating iron-deficiency anemia.
4 Textile & Other Auxiliary Applications
It can be used as a printing and dyeing mordant in textile production, and also serves as an auxiliary raw material for various synthetic resin formulations.
