Oak, have you heard that Coca-Cola, LVMH and others are all paying attention to a material called PEF?Claims to be an alternative to PET?
That's right, and it's bio-based**.
Bio-based?Are you saying it comes from renewable biomass resources?My favorite happy fat house water bottle is made of PET material, PEF, PET, what's the difference?It seems like there's just one letter missing...
To the point!The difference between PEF and PET lies in this F and T. The F in PEF refers to FDCA (furandicarboxylic acid), and the T in PET stands for PTA (terephthalic acid). FDCA, PTA and ethylene glycol are polymerized separately to form PEF and PET plastics. That's why they look and serve the same purpose.
I know that PET is a petroleum-based material, one of the five major engineering plastics, polyester fiber, slicing, blow molding, it is indispensable everywhere. That pef can be used in **?
Look at the following, the dialog box can't be put down!Oak is here to give you a pediatric science pef today
PEF mineral water bottle.
What is PEF?
Bio-based furan polyester (PEF) is based on:2,5-Furandicarboxylic acid (FDCA).It is a class of polyester obtained by polymerization of diacid monomers.
FDCA as 100% biomass monomerIt can be extracted from corn and biomass raw materials such as non-food crops, straw, and wood chips. It has similar structure and physical properties to the petroleum-based monomer terephthalic acid (TPA), which can be used to synthesize high-performance polyesters, polyamides and epoxy resins, and was identified by the U.S. Department of Energy in 2004 as one of the 12 most promising bio-based platform compounds"The Sleeping Giant".
Synthesis of PEFs.
PEF is a 100% plant-based, fully ** plastic material for a wide range of applications, such as:Bottles, packaging, films, fibers and textilesThese are the major end markets. In addition, it can also be used for:Electronics and auto parts
Carlsberg is conducting large-scale trials of its new fibre bottles, which are lined with plant-based PEF polymers that protect the taste and foaming properties of beer better than traditional fossil fuel** PET plastics.
What are the advantages of PEF?
The preparation of PEF with FDCA as the main raw material is a leap from petrochemical materials to renewable resources, which can effectively alleviate the traditional chemical industry.
Dependence on petrochemical resources provides important support for sustainable development.
PEF as an emerging bio-based polyester new material.
