ABSTRACT:
The invention provides a ball for a game having a spherical soft polyurethane foam and a surface layer of foamed polyvinyl chloride formed on the surface of the spherical body. The ball is produced by first casting the surface layer in a mold to form a hollow foamed PVC body having closed cells, and then charging a foamed polyurethane composition into the hollow thus formed, to produce a sphere of polyurethane having open cells within the surface layer. Also provided is a ball for games having a spherical body of foamed polyvinyl chloride and having a spherical cavity at the center. The ball is safe, has proper flexibility, and is not subject to punctures.
