GOLF BALL

摘要

A golf ball (10) comprising a liquid core (12) and a reaction-injection- molded (RIM) cover (16) material is disclosed. The liquid core (12) comprises a core shell (13) defining a hollow region, the hollow region containing a fluid (14). The reaction-injection-molded material may be a reaction-injection-molded polyurethane, a reaction-iajection-molded polyurea, a reaction-injection-molded polyurethane/polyurea blend, or mixtures thereof. A golf ball with a liquid core (12) and RTM cover (16) exhibits variable spin characteristics and a larger spin decay.
