Abstract:
Multi-layered, golf balls having a core made of a particle-based polyurethane foam composition are provided. The ball includes a dual-layered core having a foam inner core (center) and surrounding outer core layer. The surrounding outer core layer is preferably made from a foamed composition. In one embodiment, pre-expanded thermoplastic polyurethane foam beads containing a blowing agent are used to form the foam center and outer core. In another embodiment, pre-formed polyurethane foam particles are used in both core layers. The foam cores have good resiliency, thermal stability, and durability over a wide temperature range. The ball further includes a cover that may be multi-layered.

Claim (Index 1):
A method for producing a core assembly for a golf ball, comprising the steps of:\n i) providing a foam polyurethane material; ii) forming foam polyurethane particles from the foam polyurethane material, the particles having a mean diameter size in the range of about 0.001 to about 0.250 inches; iii) heat-pressing the foam polyurethane particles together to form a spherical inner core, the inner core having a diameter in the range of about 0.100 to about 1.100 inches and a specific gravity (SG inner ) of at least 1.10 and a center hardness (H inner core center ); and ii) forming an outer core layer comprising a foamed thermoset or thermoplastic composition, the outer core layer being disposed about the inner core and having a thickness in the range of about 0.100 to about 0.750 inches, and a specific gravity (SG outer ) and an outer surface hardness (H outer surface of OC ), wherein the SG outer , is greater than the SG inner , and the H inner core center  is in the range of about 10 to about 60 Shore C and the H outer surface of OC  is in the range of about 45 to about 96 Shore C to provide a positive hardness gradient across the core assembly.
