Abstract

La presente invencion está dirigida a una mezcla reactiva de isocianato con cantidades específicas de a) un poliol poliéter que tiene una funcionalidad de hidroxilo de 4 a 8 y que tiene un numero de hidroxilo de aproximadamente 300 a aproximadamente 450, b) un poliol poliéter que tiene una funcionalidad de hidroxilo de 4 a 8 y que tiene un numero de hidroxilo de aproximadamente 50 hasta aproximadamente 200, y en donde al menos el 75% de los grupos hidroxilo son grupos hidroxilo primarios, c) un aducto de una mono, di o trialcanolamina y oxido de propileno, dicho aducto tiene un numero de hidroxilo de aproximadamente 100 a aproximadamente 800, y d) una polioxialquilen poliamina que tiene un peso molecular de aproximadamente 2000 a aproximadamente 5000, y que contiene de 2 a 3 grupos amino primarios. La invencion también está dirigida a la fabricacion de espumas que absorben energía sopladas con agua a partir de la mezcla reactiva de isocianato.
