摘要:
The present invention is directed to golf balls consisting essentially of a dual-layer core and a cover. The core includes a center having a center hardness of 50 Shore C or greater and formed from a first HNP composition, and an outer core layer having a surface hardness of 75 Shore C or greater and formed from a second HNP composition. The first 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 second HNP composition has a material hardness of 45 Shore D or greater and comprises a highly neutralized ethylene/(meth)acrylic acid copolymer. The material hardness of the first HNP composition is less than the material hardness of the second HNP composition. The cover includes an inner cover layer formed from a thermoplastic composition and an outer cover layer formed from a polyurethane or polyurea composition.

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.

The present invention provides golf balls comprising a low specific gravity intermediate layer formed from a moisture resistant composition and disposed between a core and a cover. Depending on the thickness and specific gravity of the various layers, among other factors, the moment of inertia of the golf balls can be high or low.

The present invention is directed to golf balls consisting of a multi-layer core and a cover. The multi-layer core consists of a center and an outer core layer that are both soft relative to a hard intermediate core layer. The outer core layer is preferably thin relative to the center and the outer core layer. The multi-layer core includes at least one layer formed from a relatively soft HNP composition and at least one layer formed from a relatively hard HNP composition.

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.

Golf balls consisting of a multi-layer core and a cover are disclosed. The multi-layer core consists of a large center and a thin outer core layer that are both soft relative to a hard, thin intermediate core layer.
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.

Golf balls comprising a multi-layer core and a cover are disclosed. The multi-layer core comprises a thermoset rubber inner core, a thermoset rubber first intermediate core layer, a thermoplastic second intermediate core layer, and a thermoset rubber outer core layer. The inner core is preferably formed from a softer rubber than the first intermediate core layer.

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.
