Abstract

Se describe una mezcla de reacción para la elaboración de una espuma de poliuretano, cuya mezcla se puede obtener haciendo reaccionar un isocianato polifuncional con un compuesto reactivo al isocianato, en presencia de un agente secuestrante y al menos un catalizador; y el curado de dicha mezcla de reacción permite proporcionar una espuma con emisiones reducidas de aldehído lo cual es particularmente útil en medios de transporte, tal como para parte interior de automóviles.
