Abstract

Un elastómero de organosilicona-poliuretano termoplástico y un método de preparación del mismo. El elastómero comprende los siguientes componentes: 25-80 partes de un poliol macromolecular, 0-60 partes de un aceite de organosilicona o un caucho de silicona líquido, 10-50 partes de diisocianato, 3-20 partes de un diol micromolecular extensor de la cadena, y 0.1-3 partes de un adyuvante; el poliol macromolecular es un poliol sin solicona que tiene un peso molecular de 1000-4000 g/mol y un poliol modificado por la organosilicona a través de la copolimerización o injerto; y el diol micromolecular es un diol micromolecular que tiene 10 átomos de carbono o menos.
