Polyethylene 2,5-furandicarboxylate / PEF CAS 28728-19-0
PEF polyester is a polycondensation product of 2,5-furandicarboxylic acid (FDCA) and ethylene glycol. It can improve the gas barrier properties, hot-fill temperature, colorability, and mechanical strength of petroleum-based polyethylene terephthalate (PET), and has broad application prospects in high-barrier packaging materials, high-performance fibers, and engineering plastics. The company has completed the verification of multiple application scenarios such as PEF fiber, PEF polyester bottles, and PEF multilayer films.
Product Advantages:
100% Bio-based: Derived from renewable resources such as corn and straw.
Natural Functionality: Structure-enhanced, no chemical additives required.
Superior Multifunctionality: Comprehensive improvement in barrier properties, mechanical properties, and processability.
Compatible with PET Recycling Systems: Can be recycled alone or blended with PET for reuse.
Carbon Reduction Advantage: 43.8% lower carbon emissions per ton compared to PET.
PEF is polymerized from the bio-based monomer FDCA and ethylene glycol, with raw materials derived from renewable resources such as corn and straw. Its unique molecular structure endows the material with multifunctionality and high performance, and it excels in low-carbon sustainability, achieving a dual improvement in greenness and performance, making it an ideal bio-based alternative to petroleum-based polyester PET.
