2,5-Furandicarboxylic Acid (CAS 3238-40-2), commonly abbreviated as FDCA, is a white crystalline organic compound and a high-potential bio-based building block derived from plant sugars (fructose or glucose), primarily utilized as a sustainable alternative to terephthalic acid in the production of polyesters. This Furan-2,5-dicarboxylic acid functions as a rigid monomer in Dehydromucic acid based polymerization, enabling the synthesis of Polyethylene Furanoate (PEF)—a fully recyclable plastic that exhibits superior gas barrier properties and mechanical strength compared to conventional PET bottles. To support industrial-scale requirements, we provide bulk supply with competitive factory pricing and ensure rigorous quality control through customized specifications alongside standard technical documentation, including MSDS, TDS, COA.

FAQ - Technical & Supply Chain
-
Q:
How does FDCA (CAS 3238-40-2) compare to Terephthalic Acid (PTA) in polymer synthesis?
A: FDCA is structurally analogous to PTA but contains a furan ring instead of a benzene ring (C6H4O5); this difference results in polymers (like PEF) with significantly higher barrier resistance to oxygen and carbon dioxide, extending the shelf life of packaged beverages. -
Q:
Is this material fully bio-based?
A: Yes, industrial FDCA is typically produced via the catalytic oxidation of hydroxymethylfurfural (HMF) derived from renewable biomass sugars, making it a critical component for reducing the carbon footprint of the plastics industry.
