What Is 2,5-Furandicarboxylic Acid (FDCA)?

FDCA (CAS 3238-40-2), recognized by the U.S. Department of Energy as one of the "Top 12 Building Block Chemicals for a Green Future," is a furandicarboxylic acid with a cyclic structure and reactivity comparable to terephthalic acid (PTA), serving as a key monomer for sustainable polymer applications.

As the most in-demand furan monomer, it provides a renewable alternative or complement to aromatic petrochemicals.

lts key polymer, poly(ethylene 2,5-furandicarboxylate) (PEF), which is formed by polymerizing FDCA with ethylene glycol, delivers exceptional gas barrier properties for packaging, as well as antibacterial & mite-resistant, moisture-wicking, and UV-resistant features for fiber applications.

Beyond PEF, this renewable monomer also enables the development of bio-based nylons (PA), aramids (PPA), and elastomers, supporting a wide range of advanced polymer applications. Continuous improvements in FDCA production technology and cost efficiency are accelerating its global adoption as a sustainable and high-performance material.

FDCA vs. Petroleum-Based Chemicals

FDCA offers comparable performance with significant sustainability benefits.

Superior Properties
PEF, derived from FDCA, surpasses PET in gas barrier strength for packaging and offers natural antibacterial and mite-resistant, moisture-wicking, and UV-resistant properties for fiber applications. Continued innovation in FDCA production further enhances performance consistency and supports wider use across sustainable polymer markets.
Renewable Sourcing
As a 100% biomass-derived monomer, it highlights key advantages in sustainable material production.
Carbon Footprint Reduction
Carbon footprint ↓ 24% vs. fossil-based PTA.
Non-renewable energy use ↓ 75% vs. fossil-based PTA.
Recyclable
PEF is fully recyclable within the PET stream, enabling efficient reuse while further leveraging FDCA production scalability.
Globally Aligned
It is designed to meet stringent global regulations on sustainable materials and carbon reduction, while ensuring a competitive price for 2,5-furandicarboxylic acid and supporting broad industrial adoption.
