Abstract
Disclosed herein is a golf ball comprising fast-chemical-reaction-produced component, such as a component which comprises a reaction injection molded polyurethane material. A process of making a golf ball by forming at least one core and/or cover component of the ball by mixing two or more reactants that react and form a reaction product with a flex modulus of 5-310 kpsi in a reaction time of about 5 minutes or less, the component having a thickness of at least 0.01 inches and a demold time of 10 minutes or less is disclosed. In one preferred form of the invention, excess polyurethane from forming golf ball covers is recycled by using it to form golf ball cores.
Claims36
A process of making a conventional multi-piece golf ball having at least one uniformed, spherical cover component and core component comprising making at least one of the cover component and the core component of the ball by mixing two or more reactants that react and form a reaction product with a flex modulus of 5-310 kpsi in a reaction time of about 5 minutes or less, the at least one component having a thickness of at least 0.01 inches and a demold time of 10 minutes or less.
A multi-piece golf ball comprising a uniformed. spherical core and a uniformed, spherical cover formed thereon, wherein the core or the cover is formed from a reaction injection molded material comprising polyurethane/polyurea, wherein the polyurethane/polyurea material incorporates meta-tetramethyexylylene diisocyanate.
