Abstract
El campo técnico de aplicación de la presente invención es el de la estabilización de espumas de poliuretano. Así, un objeto de la presenteinvención es un método para estabilizar espuma de poliuretano, caracterizado por (a) soplar espuma de poliuretano con un gas inerte presurizado; y (b)agregar a la formulación de espuma un tensioactivo copolímero tipo panal de poliéter de óxido de polialquileno polisiloxano que tiene un contenido de óxidode alquileno de menos de aproximadamene 37% en peso de óxido de alquileno. Otro objeto de la presente invención es un método para usar un tensioactivo en elmétodo anteriormente descripto, caracterizado porque dicho tensioactivo es agregado a una formulación de espuma de poliuretano quees soplada con un gasinerte presurizado, comprendiendo dicho tensioactivo un copolímero tipo panal de poliéter de óxido de polialquileno polisiloxano que tiene menos de 37%en peso de óxido de etileno.
