PEF, a bio-based polymer, exhibits a higher glass transition temperature, resulting in slower crystallization and easy processing. Its melting point is lower than that of PET, enabling energy-saving, low-temperature processing for efficient bonding with other bio-based polyesters.
GS Biomats has validated its use across multiple sustainable material applications.
Why PEF outperforms traditional PET in sustainability and performance. Poly(ethylene 2,5-furandicarboxylate) (PEF) exhibits a higher glass transition temperature than PET, resulting in slower crystallization and easy processing. This high-performance, multifunctional polymer is process-compatible, recyclable, and renewable, enabling efficient integration with PET in packaging applications and enhancing fiber performance with natural antibacterial, mite-resistant, moisture-wicking, and UV-protective properties.
100% Bio-based Feedstock
Made from renewable biomass such as corn, straw, and agricultural residues, PEF offers a sustainable alternative to fossil-based PET. Sourced from 100% renewable biomass, PEF is a sustainable polymer that reduces carbon emissions by approximately 43.8% compared with PET, cutting reliance on fossil feedstocks while delivering full bio‑derived polymer credentials.
Lower Carbon Footprint
PEF reduces carbon emissions by approximately 43.8% compared with traditional PET, contributing to a lower environmental impact across its lifecycle.
Performance Upgrade
The unique oxygen-rich furan ring in PEF’s molecular backbone delivers inherent performance advantages on top of its green origin.
Recyclable in PET Stream
PEF can be recycled within existing PET streams and processed on the same production lines.
