THERMOPLASTIC MULTI-LAYER GOLF BALL

摘要

A thermoplastic multi-layer golf ball has a core center comprising a first thermoplastic material having a first flexural modulus; a core layer disposed radially outward from the core center, wherein the core layer comprises a second thermoplastic material having a second flexural modulus; and a cover disposed radially outward of the core layer, wherein the cover comprises a third thermoplastic material having a third flexural modulus. Either the second flexural modulus is greater than the first flexural modulus or both are up to about 15,000 psi. The first flexural modulus is greater than the third flexural modulus or the third flexural modulus is up to about 5,000 psi.
