InactiveUS20090209366A1Slow down the spin rateImprove wear resistanceGolf ballsSolid ballsEngineeringHardness
The invention provides a golf ball composed of a core, a cover having a plurality of dimples on an outside surface thereof, and an intermediate layer disposed between the core and the cover. The core has a deflection, when compressed under a final load of 130 kgf from an initial load of 10 kgf, of at least 3.0 mm but not more than 5.0 mm. The intermediate layer is formed of a highly neutralized resin material, and has a Shore D hardness of at least 40 but not more than 60 and a thickness of at least 1.7 mm but not more than 4.0 mm. The number of dimples is at least 272 but not more than 348. The golf ball, through a combination of dimples which do not cause a loss of lift in the low-velocity, low-spin rate region of the ball trajectory and a low-spin construction, travels farther and is therefore beneficial for competitive use by both skilled and amateur golfers.
