Abstract

Método para volver a tratar material de desecho curado celular producido de la reacción de agua, poliisocianato y un material polímero que contiene hidrógeno activo que tiene un peso molecular promedio de desde aproximadamente 1000 a 5000 y un índice ácido no mayor de 5, caracterizado por la operación de disolver hasta el 50% en peso del material celular flexible en un material polímero líquido que contiene hidrógeno activo que tiene un peso molecular promedio de desde aproximadamente 1000 a 5000 y un índice ácido no mayor de 5, calentando hasta que el material celular de desecho curado se disuelva en el líquido, añadiendo subsiguientemente agua y poliisocianato al líquido y permitiendo que se espume y cure.
