Polyol formulation comprising:n (a) 80 to 99.5 parts by weight (pbw) of a polymer polyol comprising a base polyol having a molecular weight in the range of from 2,500 to 6,500, an average nominal functionality (Fn) of at least 2.0 and a primary hydroxyl content of at least 40% and a polymer stably dispersed therein; and, up to a total of 100 pbw, (b) 0.5 to 20 pbw of a hydrophilic polyol having a molecular weight in the range of from 2,000 to 5,500, an ethylene oxide content of at least 40% by weight and a primary hydroxyl content of at least 50%. n The formulation may further comprise a catalyst, preferably including a tin catalyst, and optionally a crosslinking agent and is very useful for producing latex-like polyurethane foams. Such foams may be suitably applied in cushions (in e.g. car seats and upholstered furniture) or mattresses. |
