Major Application Areas
1
Bio-based Polyesters (Core Application)
PEF (Polyethylene furanoate): Polymerized with ethylene glycol, PEF offers gas barrier properties (O₂/CO₂/H₂O) 2–10 times higher than PET, along with superior heat resistance and mechanical performance. It is used in beverage bottles, food packaging, films, and fibers.
Other Bio-based Polyesters: Includes PPF, PTF, etc., utilized in high-end packaging, textiles, and automotive interiors.
2
Engineering Plastics & Resins
Polymer Modification: Used in semi-aromatic nylons, unsaturated polyesters, and polyurethanes to enhance heat resistance, chemical resistance, and barrier properties.
Coatings & Adhesives: Applied in high-performance coatings, adhesives, and composites to improve weatherability and adhesion.
3
Eco-friendly Plasticizers
Non-phthalate Synthesis: Used to synthesize bio-based non-phthalate plasticizers, serving as a substitute for traditional phthalates in PVC, food packaging, and medical supplies.
4
Other Applications
Chemical Synthesis: Serves as a raw material for Metal-Organic Frameworks (MOFs), pharmaceutical intermediates, and functional materials.
Polymer Modification: Acts as a modifier for petroleum-based polymers to improve biodegradability and environmental friendliness.

Frequently Asked Questions (FAQ)
Q
What is FDCA and where does it come from?FDCA (2,5-Furandicarboxylic acid) is a bio-based dicarboxylic acid derived from renewable biomass feedstocks such as glucose and fructose. It is 100% bio-based and biodegradable, making it a green alternative to petroleum-derived purified terephthalic acid (PTA).
Q
How does PEF compare to traditional PET in terms of performance?PEF (Polyethylene Furanoate), synthesized from FDCA and ethylene glycol, offers gas barrier properties (O₂, CO₂, H₂O) that are 2–10 times superior to conventional PET. It also demonstrates better heat resistance and mechanical strength, making it an ideal material for beverage bottles, food packaging, and films.
Q
Is FDCA compliant with food contact and medical application standards?Yes. FDCA is fully compliant with RoHS and REACH regulations and contains no harmful residues. This makes it suitable for high-end applications including food contact materials and medical sector products.
Q
What polyols can FDCA be polymerized with?FDCA can efficiently polymerize with a range of polyols, including ethylene glycol (to form PEF), propylene glycol (to form PTF), and other diols. It serves as a key monomer for producing various bio-based polyesters and polyamides used across multiple industries.
Q
How should FDCA be stored to maintain its quality?FDCA should be stored in a cool, dry, and well-ventilated environment. The packaging must remain sealed and kept away from oxidants, acids, and bases to prevent degradation and maintain product integrity over time.
Q
What are the packaging specifications for FDCA?FDCA is supplied in 25 kg bags. The product appears as a white powder with a purity of greater than 99.5% (by HPLC), ensuring consistent quality for industrial polymerization and chemical synthesis applications.
