  • Patent number: 6068790
    Abstract: A polyol formulation is disclosed, the formulation including: (a) 80 to 99 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, an ethylene oxide content of 50 to 80%, and a primary hydroxyl content of at least 40% and a polymer stably dispersed therein; and, up to a total of 100 pbw, (b) 1 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%. The formulation may further include a tin catalyst and optionally a crosslinking agent and is very useful for producing latex-like polyurethane foams. These foams may be suitably applied in cushions (in e.g. car seats and upholstered furniture) or mattresses.
