Abstract: Golf balls having cores with increased hardness gradients and improved impact durability are provided. The cores have an increased “positive” hardness gradient (or a “hard-to-soft” hardness) where the outer surface of the core is harder than the center. The cores are formed from rubber formulations including combinations of a terpene-based resin, ethylene-propylene-diene (EPDM) rubber, and/or a water releasing agent. The resulting golf balls have increased impact durability and resilience.

Abstract: In a golf ball having a core and a cover with a plurality of dimples on the surface, the cover is formed primarily of polyurethane, the dimples have a specific volume occupancy ratio and the ball has a diameter of at least 42.8 mm. In an impact test carried out by hitting the ball with a driver at a head speed of 40 m/s, the sum t1+t2 of the time t1 required from initial contact by the driver with the ball for deformation of the ball to reach a maximum and the time t2 required from the state of maximum ball deformation for the ball and driver to separate is 660 μsec or less. This golf ball makes it possible for golfers who have a high head speed and ordinary golfers who do not to compete without relying excessively on superiority in terms of distance.

Abstract: Golf ball comprising layer formed from polymer composition comprising delignified natural wood. The delignified natural wood may be basswood, oak, poplar, ash, alder, aspen, balsa wood, beech, birch, cherry, butternut, chestnut, cocobolo, elm, hickory, maple, oak, padauk, plum, walnut, willow, yellow poplar, bald cypress, cedar, cypress, fir, hemlock, larch, pine, redwood, spruce, tamarack, juniper, yew, and/or bamboo and having a lignin content of less than 20 wt %. Hemicellulose content may be less than 30 wt %, or about 15 wt % or less, or less than 15 wt %. The delignified natural wood is included in the polymer composition in an amount of 20 wt % or less, based on total weight of the polymer composition. Examples of polymer compositions include rubbers, polyurethanes, polyureas, ionomers, and combinations thereof. In specific embodiments, the golf ball core and/or intermediate layer is formed from the polymer composition. The delignified wood may comprise chopped wood pieces and/or powder.

Abstract: Compositions including a hardness agent and golf ball cores made from such compositions having a tailored hardness gradient are disclosed. The type and concentration of the components in the composition, including the hardness agent, affects the hardness, hardness gradient, and compression of cores made from the composition and, thus, can be used to produce a golf ball having desirable performance characteristics.
