English description（英文原文，共 1252 字符）
Product Name:Poly(ethylene 2,5-furandicarboxylate)
English Name:Poly(ethylene 2,5-furandicarboxylate)
CAS No.:28728-19-0
Molecular Formula:(C8H6O5)n
Physical Properties:Light yellow to colorless transparent solid particles; glass transition temperature about 86°C, melting point about 235°C, density about 1.40 g/cm³; barrier properties to O2, CO2, and H2O are 7 times, 15-20 times, and more than 2 times that of PET, respectively; crystallization rate is lower than that of PET.
Uses:PEF is a bio-based polyester mainly used in high-performance packaging materials (such as beverage bottles and food packaging) and functional fibers, with excellent gas barrier properties and heat resistance, and can partially replace PET. In the fiber field, it exhibits advantages such as moisture wicking and quick drying, natural antibacterial activity, UV resistance, and pilling resistance, while being compatible with PET processes and equipment for convenient recycling.
Technical Specifications:
Purity: 99%
Appearance: light yellow/colorless transparent solid particles
Glass transition temperature: 86°C
Oxygen barrier: >7 times PET; carbon dioxide barrier: 15-20 times PET; water vapor barrier: >2 times PET
Crystallization time: >1.5 times PET
