ABSTRACT:
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.
