FOERFARANDE FOER FRAMSTAELLNING AV MATTA, VID VARANDRA ICKE FAESTANDE TUNNVAEGGIGA FORMSTYCKEN AV LINEAERA, THERMOPLASTIC, POLYADDUKTER INNEHAOLLANDE POLYURETANELASTOMERER OCH DERAS ANVAENDNING.

摘要

The present invention is directed to a process for the production of matte, non-blocking, thin-walled molded articles, films or tubes from polyurethane elastomers prepared from high molecular weight polyols which contain dispersed polyadducts based on polyisocyanate polyaddition products. The use of these high molecular weight polyols contained dispersed polyadducts allows for the preparation of thin-walled, molded articles which have reduced surface tackiness. The present invention is additionally directed to the molded articles produced by this process and to their use for forming polyurethane foam composites.
