Process for producing a golf ball |
摘要 |
Disclosed is a process for producing a golf ball having a cover formed from a thermoplastic polyurethane material which can be recycled for molding, which exhibits high restitution, and which exhibits excellent scuff resistance. The production process includes preparing a cover-forming material (C) by incorporating the following component (B) into the following component (A); and subjecting the cover-forming material (C) to injection molding, to thereby form a cover around the core: (A) a thermoplastic polyurethane material, and (B) an isocyanate mixture in which an isocyanate compound (b-1)) having at least two isocyanate groups serving as functional groups in the molecule is dispersed in a thermoplastic resin (b-2) which is substantially non-reactive with the isocyanate groups. |
