摘要: Molded polyurethane seating foams exhibiting low resonant frequencies and low ball rebound are produced by reacting an isocyanate-terminated prepolymer prepared from a polyol component comprising in major part one or more low intrinsic unsaturation substantially polyoxypropylene polyols and/or polymer polyols with a blowing/chain extending stream comprising water and optionally amines and alkanolamines.
