Abstract

1. "Procedimiento para la fabricación por moldeo de piezas de forma", según el cual se dispondrán o colocarán en el molde apropiado una esterilla de fibras y una mezcla reactiva de poliol, isocianato y eventualmente otros determinados aditivos, cuyos espacios huecos del molde se rellenarán configurando o conformando la figura de la pieza de forma moldeada que será acabada paralelamente al desplazamiento que produce la reacción química de la espuma integral, caracterizado por cuanto, dicha mezcla reactiva se combinará con un 5 a un 30 por ciento de su peso de un éster neutro con un punto de ebullición superior a la temperatura de reacción de la espuma reactiva.
