Partial glycolysis (transesterification with ethylene glycol) converts the rigid polymer into short-chained oligomers that can be melt-filtered at low temperature. Recently, molecular level stabilization of the material using nanostructured chemicals has also been considered. This aim is solved by degrading the PET bottle flakes—already during their first plasticization, which can be carried out in a single- or multi-screw extruder—to an intrinsic viscosity of about 0.30 dℓ/g by adding small quantities of ethylene glycol and by subjecting the low-viscosity melt stream to an efficient filtration directly after plasticization. Also as above, polyethylene terephthalate can be hydrolyzed to terephthalic acid and ethylene glycol under high temperature and pressure. When using directly secondary materials such as bottle flakes in spinning processes, there are a few processing principles to obtain. Mechanical recycling or direct circulation of PET in the polymeric state is operated in most diverse variants today. We're doing our best to make sure our content is useful, accurate and safe.
