摘要:
A golf ball comprising a core and a cover layer, wherein the cover layer provides one or more deep depressions that extend through the cover layer to and/or into a layer or component underneath is disclosed. The cover may be a single layer or it may include multiple layers. If the cover is a multi-layer cover, the deep depressions extend to or into at least the first inner cover layer, and may extend to and/or into two or more inner cover layers. If the cover is a single layer, the deep depressions extend to and/or into the core. The cover layer(s) may be formed from any material suitable for use as a cover, including, but not limited to, ionomers, non-ionomers and blends of ionomers and non-ionomers. The deep depressions may be spherical or non-spherical, and the portion of the deep depression that extends to or into the next inner layer may be the same or different shape as the outer portion of the deep depression.

A golf ball component, such as a golf ball cover layer, formed from a high or increased melt index thermoplastic polyurethane, polyurea or polyurethane/polyurea is disclosed. The cover layer may be relatively thin (i.e., 0.075 or less, preferably 0.050 inches or less, more preferably less than 0.040 inches, even more preferably less than 0.030 inches). In addition, an operation in which the outer cover is exposed to an isocyanate solution is described to improve certain physical properties of the resulting golf ball.

A golf ball (20) approaching zero land area is disclosed herein. The golf ball (20) has an innersphere with a plurality of lattice members (40) and a plurality of deep depressions (99). Each of the plurality of lattice members (40) has an apex and the golf ball (20) of the present invention conforms with the 1.68 inches requirement for USGA-approved golf balls. The interconnected lattice members (40) preferably form a plurality of polygons, preferably hexagons and pentagons. Each of the lattice members (40) preferably has a continuous contour.

A golf ball comprising a core and a cover layer, wherein the cover layer provides one or more deep dimples that extend through the cover layer to and/or into a layer or component underneath is disclosed. The cover may be a single layer or it may include multiple layers. If the cover is a multi-layer cover, the dimples extend to or into at least the first inner cover layer, and may extend to and/or into two or more inner cover layers. If the cover is a single layer, the dimples extend to and/or into the core. The cover layer(s) may be formed from any material suitable for use as a cover, including, but not limited to, ionomers, non-ionomers and blends of ionomers and non-ionomers. The dimples may be spherical or non-spherical, and the portion of the dimple that extends to or into the next inner layer may be the same or different shape as the outer portion of the dimple. Optionally, a moisture barrier layer may be present between the core and/or the cover layer(s).

摘要:
Disclosed herein is a golf ball comprising fast-chemical-reaction-produced component, such as a component which comprises a reaction injection molded polyurethane material. The golf ball has excellent light stability. Also disclosed is a method making a golf ball by forming a cover component of the ball by mixing two or more reactants that react and form a reaction product with a flex modulus of from about 1 to about 310 kpsi in a reaction time of about 5 minutes or less, the component having a thickness of at least 0.01 inches and a demold time of 10 minutes or less.
