Abstract

Se describe un proceso para preparar espumas de poliuretano rígidas de celdas abiertas haciendo reaccionar poliisocianatos con un poliol en presenciade un agente de soplado, usualmente agua y un agente de formacion de celdas abiertas. Dichoagente comprende una combinacion de unpolialquilenpolisiloxano que tiene un punto de turbidez no mayor de 65°C y una segunda sustancia que tiene una energía libre crítica de superficie menor queaproximadamente 23mj/m2. Muy preferentemente serequier e un segundo componente polimérico, como poli(tetrafluoroetileno) en partículas finas. También sonobjetos las espumas de poliuretano obtenidas con dicho proceso y las composiciones de polioles y las composiciones depoliisocianato utiliza bles endicho proceso.
