ABSTRACT:
A ball is provided which includes a rigid core surrounded by an outer layer of foamed polyurethane. The core and outer layer are preferably both integral spheres, i.e. are not formed from separate hemispheres.
In preferred embodiments, the core is expanded polystyrene, and the outer layer is formed of an integral skin foam, i.e., a foam having a smooth non-porous skin over a microcellular open cell foam, and the foam is the reaction product of a MDI prepolymer, e.g., diphenylmethane diisocyanate prepolymer, and a urethane resin.
