PolyEthylene Furanoate (PEF)
PolyEthylene Furanoate (PEF) is a novel, bio-based polymer that is being touted as a sustainable alternative to polyethylene terephthalate (PET). PEF is produced from renewable resources and has outstanding properties that make it an attractive option for various industries, especially packaging.
Structure and Production of PEF
PEF is produced from the polymerization of furan-2,5-dicarboxylic acid (FDCA) and ethylene glycol. FDCA is a bio-chemical produced from plant sugars such as glucose.
Outstanding Features of PEF
Sustainable and Bio-based: PEF is produced from renewable resources and is biodegradable at the end of its useful life.
Superior Mechanical Properties: PEF has higher tensile strength, greater transparency, and a better barrier to gases and water vapor than PET. These properties make PEF very suitable for food and beverage packaging applications.
High transparency: PEF has a transparency similar to PET and is ideal for the production of transparent bottles and containers.
High thermal resistance: PEF has a higher thermal resistance than PET, which allows it to be used in high-temperature applications.
PEF applications
Packaging: Production of beverage bottles, food containers, packaging films and protective coatings.
Fibers: Production of fibers for the textile industry.
3D printing: Use as a raw material in 3D printing.
Coatings: Use as a protective coating for metals and other materials.
