Core Product Features
🌿
1. Bio-based & Green Attributes
Derived from biomass feedstocks like glucose and fructose, it is 100% renewable and biodegradable. It serves as a sustainable alternative to petroleum-based PTA, significantly reducing the carbon footprint.
🔬
2. Structural Advantages
The unique furan ring and dicarboxyl structure endow downstream materials with superior gas barrier properties, heat resistance, and mechanical strength—outperforming traditional PET.
⚗️
3. Polymerization Compatibility
It efficiently polymerizes with polyols such as ethylene glycol and propylene glycol, serving as a key monomer for synthesizing bio-based polyesters and polyamides.
✅
4. Eco-friendly Compliance
Fully compliant with RoHS and REACH standards with no harmful residues, making it suitable for high-end applications like food contact and medical sectors.
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. 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)
❓What is FDCA and what is it made from?
FDCA (2,5-Furandicarboxylic Acid) is a bio-based dicarboxylic acid derived from renewable biomass feedstocks such as glucose and fructose. It is a 100% renewable and biodegradable compound that serves as a green alternative to petroleum-based purified terephthalic acid (PTA).
❓How does PEF compare to traditional PET plastic?
PEF (Polyethylene Furanoate), synthesized from FDCA and ethylene glycol, offers gas barrier properties (O₂, CO₂, H₂O) that are 2–10 times superior to traditional PET. It also demonstrates better heat resistance and mechanical performance, making it an excellent candidate for beverage bottles, food packaging, films, and fiber applications.
❓Is FDCA compliant with food contact and medical regulations?
Yes. FDCA is fully compliant with RoHS and REACH standards and contains no harmful residues. This makes it suitable for high-end applications including food contact materials and medical-grade products.
❓What is the purity level of your FDCA product?
Our FDCA product has a content (measured by HPLC) of greater than 99.5%, with heavy metals ≤2.0 mg/kg, loss on drying ≤0.5%, and ash ≤2.0%. It appears as a white powder meeting strict quality specifications.
❓How should FDCA be stored and what is the packaging?
FDCA should be stored in a cool, dry, and well-ventilated environment, kept sealed and away from oxidants, acids, and bases. It is packaged in 25 kg bags to ensure safe handling and transportation.
❓Can FDCA be used in applications beyond polyester production?
Absolutely. Beyond bio-based polyesters like PEF, PPF, and PTF, FDCA is also used in engineering plastics, high-performance coatings and adhesives, eco-friendly non-phthalate plasticizers for PVC, Metal-Organic Frameworks (MOFs), pharmaceutical intermediates, and as a modifier for petroleum-based polymers to enhance biodegradability.
