Disclosed herein is novel thermoplastic material and a golf ball utilizing the thermoplastic material. The golf ball ( 10 ) preferably comprises a core ( 12 ), a cover ( 16 ) and optionally a boundary layer ( 14 ). At least one of the core ( 12 ), cover ( 16 ) or boundary layer ( 14 ) of the golf ball ( 10 ) comprises the thermoplastic material. The thermoplastic material comprises a partially to highly neutralized blend of copolymers additionally comprising a fatty acid or fatty acid salt, and a heavy mass filler in an amount ranging from 10 parts by weight to 50 parts by weight of the material, with the heavy mass filler having a density greater than the copolymer. The golf ball component of the invention has soft feel and resilience that is maintained or improved. |
