Claim Text:
1. A golf ball, comprising: a core center having a diameter of from about 28 mm to about 35 mm and a specific gravity of up to 0.95 comprising a first thermoplastic material having a first flexural modulus of less than about 15,000 psi, wherein the core center is foamed or comprises hollow glass particles; a core layer disposed radially outward from the core center comprising a second thermoplastic material having a second flexural modulus of up to about 15,000 psi, wherein the second flexural modulus is greater than the first flexural modulus; and a cover disposed radially outward from the core layer, wherein the cover has a specific gravity of at least about 2, a third flexural modulus of at least about 15,000 psi, a thickness of at least about 2 mm, and comprises a third thermoplastic material, such that the specific gravity of the cover is at least about 1.05 greater than the specific gravity of the core center.
