DuPont’s new polyol is aimed at elastomers, TPU and coating but spandex fibres are also a target
What’s novel about DuPont’s new Cerenol range of high-performance polyether diols is not only that they are made from a renewable resource – the company’s Susterra 1,3 propanediol (PDO), produced via fermentation of corn sugar – but more importantly that they are high-quality products aimed at higher formance applications.
One of these uses, some way down the road yet, lies in spandex PU fibres, a product that demands exceptional quality and performance, DuPont executives told Urethanes Technology International, in a 6 Oct interview during the meeting of the US Center for the Polyurethanes Industry, in National Harbor, Maryland.
Another novel aspect of the diols is that they might never have seen the light of day had DuPont not divested a large business making a competing product, PTMEG (polytetramethylene ether glycol).
Typical PU outlets for DuPont’s new polyether diols are in elastomers, copolyether thermoplastic elastomers and coatings.
DuPont has been supplying samples from a “relatively small unit down in Mississippi,” said Ray Miller, Cerenol global business manager with DuPont’s Applied BioScience’s unit.
But it is now, “starting a commercial-scale unit,” Miller said, and will be making products available for “customers that are ready to go.” The new unit will make about 1000 tonnes initially, starting late December,…
