    Abstract: Disclosed is 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 cover is formed from a composition (C) containing, as predominant components, the following components (A) and (B): (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.

    Abstract: A mixture having good thermal stability, flow and moldability and suitable as a golf ball-forming material is obtained when a resinous component including a base resin of an ionomer resin or resins and optionally a non-ionomer thermoplastic elastomer is blended with specific proportions of a fatty acid and/or fatty acid derivative and a basic inorganic metal compound capable of neutralizing acidic groups left unneutralized in the base resin and fatty acid. Using the same material, high-rebound golf balls can be effectively manufactured.

    Abstract: In a golf ball comprising a core and a cover, the cover is formed of a cover stock based on a mixture of an ionomer resin and a thermoplastic polyurethane elastomer and having a hardness of at least 55 as measured by a ASTM D2240 type D durometer. The cover stock avoids any discoloration upon long-term UV exposure and is easy to mold. The ball has advantages including moderate backspin upon driver shots, good travel distance performance, and durability against repetitive hits.
