    摘要： The subject invention provides a viscoelastic polyurethane foam being flame retardant and having a density of greater than two and a half pounds per cubic foot that comprises a reaction product of an isocyanate component, an isocyanate-reactive blend, and a chain extender. The isocyanate-reactive blend includes a first isocyanate-reactive component and a second isocyanate-reactive component. The first isocyanate-reactive component includes at least 60 parts by weight of ethylene oxide (EO) based on 100 parts by weight of the first isocyanate-reactive component and the second isocyanate-reactive component includes at most 30 parts by weight of EO based on 100 parts by weight of the second isocyanate-reactive component. The chain extender is reactive with the isocyanate component and has a backbone chain with from two to eight carbon atoms and is present in an amount of from 5 to 50 parts by weight based on 100 parts by weight of the foam. A composition useful in making the viscoelastic polyurethane foam is also disclosed.

    摘要： A polyol composition is provided which when reacted with and organic isocyanate, has good flow characteristics and makes an all water blown rigid polyurethane foam having good dimensional stability at low core densities of 1.1 pcf to 2.0 pcf. The polyol composition has a polyol component which must have present a polyoxyalkylene polyether polyol having an equivalent weight of 130 or less, an average functionality of 3.1 or greater, and a hydroxyl number of 400 or more, a polyoxyalkylene polyether polyol having an average functionality from 1.5 to 3.1 and a viscosity of less than 800 cP at 25.degree. C., and a polyoxyalkylene polyether polyol having an average functionality of greater than 3.1 and an equivalent weight of greater than 130. The polyol composition also has water as the blowing agent, and further contains a blow catalyst, a delayed action gel catalyst, and preferably a cure catalyst and a surfactant.
