Process for making low density flexible polyisocyanurate-polyurethane foams |
摘要 |
Low density flexible molded and slabstock foams are prepared by reacting a polyisocyanate with a polyol composition containing a mono-alcohol. The blowing of the foam is essentially with carbon dioxide generated from the reaction of water with isocyanate, and the reaction catalysts used in the preparation of the foam include a polyisocyanate trimerization catalyst.
