摘要: Flexible polyurethane foams are prepared using certain high molecular weight, functionality poly(oxyethylene) compounds as cell openers and softeners. These polyether polyols have been found to be very effective in opening the cells of foam, even when used making based on PIPA polyols, which notoriously closed-celled. They also quite softening made MDI-based polyisocyanates.
