“Gist”: F-TPUs are prepared by incorporating perfluoro diols
Why it is interesting: The current inventions are about fluorinated TPU and its applications. The F-TPUs are prepared by replacing part of the polyol with hydroxyl-ended fluorinated polyethers. In the examples fluorinated polyether diols are used in different ratios to conventional polyester-, PTMEG-, CAPA- and polycarbonate diols and reacted with MDI or HDI and BDO or HDO as chain extenders. The F-TPUs can be used as uppers for footwear and as cases for smartphones and are said to have improved stain resistance and – surprisingly- a soft feel to the touch.
