An integral skin polyurethane steering wheel is prepared by reacting (a) a mixture of a graft polymer dispersion in a polyol or a polyol mixture (b) an organic polyisocyanate selected from the group consisting of an isocyanate prepolymer prepared by reacting 4,4'-diphenylmethane diisocyanate with a mixture of dipropylene glycol and a polyoxypropylene glycol having a molecular weight of about 420, a polymeric polymethylene polyphenylene polyisocyanate containing about 55 weight percent diphenylmethane diisocyanate, a 1:1 mixture of 2,4'and 4,4'-diphenylmethane diisocyanate and mixtures thereof, (c) a blowing agent, (d) a chain extender, and (e) a catalyst, surfactant and optionally flame retardants, fillers U.V. adsorbers and other additives.

Process for the preparation of integral skin polyurethane steering wheels

A RIM polyurethane elastomer prepared by reacting an organic polyisocyanate, a polyoxyalkylene polyether polyol, and a chain extender. The polyol contains from about 7 weight percent to about 40 weight percent ethylene oxide either as a block or a heteric structure.
