Abstract

La presente invención se refiere al campo del poliuretano, especialmente se refiere a un prepolímero terminado en isocianato, al procedimiento para prepararlo y al uso del mismo. La presente invención ajusta los componentes de reacción y las proporciones de los mismos para obtener un prepolímero terminado en isocianato adecuado para preparar una espuma de poliuretano flexible, a una temperatura del molde relativamente baja. El procedimiento para preparar una espuma de poliuretano flexible usando el prepolímero terminado en isocianato proporcionado en la presente invención puede reducir la temperatura del molde, el tiempo de producción y el consumo de energía, así como obtener un procesamiento de la espuma flexible de poliuretano con buenas propiedades físicas y mecánicas.
