摘要:
A golf ball having a cover layer, an outer core layer, and an inner core layer. The inner core layer has a first compression deformation at 24° C. and a second compression deformation at 70° C. The ratio between the second compression deformation and the first compression deformation is between approximately 1.5 and approximately 2.5.

A golf ball having a core layer, a mantle layer enclosing the core layer, and a cover layer enclosing the mantle layer. At least one of the layers includes a blend of at least two highly neutralized acid polymers having low flexural moduli. The relative proportion of one highly neutralized acid polymer to the other highly neutralized acid polymer is between about 10:90 and about 90:10.

A four piece golf ball includes several relationships among the values of the densities of its layers. Namely, the sum of the density of the inner core and the outer core is at least 2 g/cm3, the sum of the density of the inner cover layer and the outer cover layer is at least 2.2 g/cm3, and the difference between these two sums is at least 0.1 g/cm3. The inner core is made of a highly neutralized acid polymer, the outer core is made of a polybutadiene rubber, and the inner and outer cover layers are made of a non-ionomeric thermoplastic material, such as thermoplastic polyurethane. The layers may have certain relationships among their hardness values. Finally, the golf ball exhibits certain physical properties, such as a certain moment of inertia.

A golf ball having an inner core layer, an outer core layer enclosing the inner core layer, and a cover layer enclosing the outer core layer. The inner core layer includes a blend of a first highly neutralized acid polymer having a first Vicat softening temperature and a first specific gravity, a second highly neutralized acid polymer having a second Vicat softening temperature and a second specific gravity, and an ionomer-based masterbatch comprising an additive and an ionomer resin having a third Vicat softening temperature and a third specific gravity. The absolute values of the differences among the Vicat softening temperatures is no more than about 15° C. and the absolute value of the difference between the specific gravities is no more than about 0.015. The cover layer may include an inner cover layer enclosing the outer core layer and an outer layer enclosing the inner cover layer.

摘要:
A golf ball having certain relationships and values of its initial velocities at various club head speeds is provided. The golf ball may achieve an initial velocity of at least about 173 mph at a club head speed of about 125 mph, therefore achieving an increased total shot distance. The golf ball has multiple layers making up its core, and the golf ball may be a four piece golf ball.
摘要:
A golf ball having certain relationships and values of its initial velocities at various club head speeds is provided. The golf ball has a typical initial velocity at a low club head speed, but an increased initial velocity at a high club head speed. Therefore, the golf ball may be advantageously used by both amateur golfers having lower swing speeds and professional golfers having high swing speeds. The golf ball may also achieve an initial velocity of at least about 173 mph at a club head speed of about 125 mph, therefore achieving an increased total shot distance.
