Abstract
131A"<D>. As espumas de poliuretano tendo baixos vação de um poliisocianato orgânico com um materialio reativos com isocianatos e um valor de OH de cerca de 200 a cerca de 650, na presença de um agente de insuflação. O agente de insuflação é mistura do que 1,0% em peso (com base no peso total da mistidas são caracaterizadas por uma condutividade térmica de menos que cerca de 0,1937 Cal-cm/h.cm²°C (0,160 Btu-in./h/ft²°F), de preferência menos que cerca de 0,1816 Cal-cm/h.cm²°C (0,150 Btu-in./h.ft materiais isolantes.
