UV Crosslinkable TPU

Title: BREATHABLE AND CROSSLINKABLE THERMOPLASTIC POLYURETHANE

 Number/Link:  WO2015/164695

Applicant/Assignee: Lubrizol

Publication date: 29-10-2015

Gist”: TPU composition containing unsaturated polyester diol and long chain monol

Why it is interesting: A soft, plasticizer-free, TPU with low processing temperature and curable by UV light can be produced by incorporating an unsaturated polyester diol and a linear C20-C65 monol. The unsaturated polyester can e.g. be prepared from butanediol, adipic acid and some trimethylolpropane monallylether.  The TPU is said to be especially useful as UV curable adhesive for fabrics.
