GOLF BALL HAVING MULTIPLE DIMPLES AND/OR MULTIPLE LAYERS OF DIFFERENT HARDNESS CAPABLE OF AFFECTING GOLF BALL FLIGHT AND GOLF BALL SENSATION

摘要

PURPOSE: A golf ball is provided to achieve the balance between sense requirement and performance by providing different materials and dimple types.;CONSTITUTION: A golf ball comprises an inner core(102), an outer core layer, a mantle layer(104), and a cover layer(106). The inner core is made of a thermoplastic material. The outer core layer includes polybutadiene rubber-containing material. The surface hardness of the outer core layer is 50-64 Shore D. The thickness of the outer core layer is 4-10 mm. The outer core layer surrounds the inner core. The mantle layer includes thermoplastic polyurethane-containing materials. The surface hardness of the cover layer is 44-60 Shore D.;COPYRIGHT KIPO 2012
