Abstract
This invention is directed to golf balls including one or more foamed, microcellular materials. The invention also encompasses methods of controlling or adjusting one or more material properties or the weight distribution of a golf ball, and methods of forming golf balls including such microcellular materials.
Claims14
A golf ball comprising:
- at least one core layer;
- and
- at least one cover layer disposed over the at least one core layer, with the at least one cover layer having a thickness of at least about 0.03 inches, wherein at least one of the core layers or cover layers is formed of a microcellular composition having an average cavity density of about 105 cavities/cm3 to 1014 cavities/cm3, and an average cavity diameter of less than about 100 microns.
A golf ball having an Atti compression of at least about 50 and a coefficient of restitution of at least about 0.7 at 125 ft/sec that comprises:
- a solid core having a deflection of about 1 mm to 6 mm under a load of 100 kg;
- and
- at least one cover layer disposed over the core and being formed of a microcellular composition having an average cavity density of about 105 cavities/cm3 to 1014 cavities/cm3, and an average cavity diameter of less than about 100 microns.
A golf ball having an Atti compression of at least about 50 and a coefficient of restitution of at least about 0.7 at 125 ft/sec that comprises:
- a core;
- an inner cover layer disposed over the core and being formed of a microcellular composition having an average cavity density of about 105 cavities/cm3 to 1014 cavities/cm3, and an average cavity diameter of less than about 100 microns;
- and
- an outer cover layer disposed over the inner cover layer and having a flexural modulus of about 10,000 psi to 70,000 psi.
