    摘要: The present invention is directed to golf balls consisting of a dual-layer core and a cover. The core consists of a layer formed from a relatively soft HNP composition and a layer formed from a relatively hard HNP composition. The relatively soft HNP composition has a material hardness of 55 Shore D or less and comprises a highly neutralized ethylene/(meth)acrylic acid/alkyl (meth)acrylate copolymer. The relatively hard HNP composition has a material hardness of 45 Shore D or greater and comprises a highly neutralized ethylene/(meth)acrylic acid copolymer. The cover preferably consists of a single cover layer.

    摘要: Golf balls having a multi-layer core and a cover are disclosed. The multi-layer core contains a center and an outer core layer that are both soft relative to a hard intermediate core layer. The outer core layer is thin relative to the center and outer core layer. In one embodiment, the relatively hard intermediate core layer has a surface hardness of 80 to 90 Shore C which is greater than the center hardness and surface hardness of the outer core layer. In another embodiment, the cover includes an inner cover layer having a surface hardness of 60 Shore D or greater and an outer cover layer having a surface hardness of 20 to 70 Shore D.

    摘要: A golf ball including a core having a compression of about 50 or less and a COR of 0.800 or greater, a thermoset polyurea cover having a hardness of 64 Shore D or less and a thickness of 0.02 inches to 0.1 inches, and an intermediate layer disposed between the core and the cover, the intermediate layer having a thickness of 0.110 inches or greater and comprising a partially- or fully-neutralized ionomer. A combination of the core and the intermediate layer has a compression of 60 or greater and the golf ball has a COR of 0.805 or greater when measured at an incoming velocity of 125 ft/s and greater than 0.75 when measured at an incoming velocity of 160 ft/s.

    摘要: A golf ball is provided having a modified density gradient among the inner layers to produce a desired high or low moment of inertia and controlled spin rate is disclosed. The golf ball has three or more inner layers in addition to a cover, and the density of the inner layers is selected such that the layers inside the cover have a density progression from the core to the cover or from the cover to the core.

    摘要: The present invention is directed to an improved golf ball displaying the desired spin profile and having a generally rigid, thermoset polybutadiene outer core surrounding a relatively soft, low compression inner core. In general, this golf ball has an inner core and at least one outer core layer surrounding the inner core. The inner core has a hardness less than a hardness of the outer core and a specific gravity less than or equal to the outer core specific gravity. Overall the inner core compression and outer core are formulated to provide a combined overall core compression of greater than about 50, preferably greater than about 70. A cover layer is provided to surround and to cover the outer core layer.
