Abstract
A golf ball comprising an innermost core, an outer core, and a cover is disclosed. At least a layer of the golf ball is made from a low compression, high coefficient of restitution material, and is being supported by a low deformation, high compression layer. The resulting golf ball has high coefficient of restitution at high and low impact speeds and low compression for controlled greenside play.
Claims7
A golf ball comprising:
- an innermost core having a compression of greater than about 60, a flexural modulus of from 75,000 psi to 225,000 psi, and a Shore C hardness of greater than 70;
- a cover;
- and an intermediate layer disposed between the innermost core and the cover, the intermediate layer comprising a rubber composition containing a halogenated organosulfur compound and having a Shore C hardness of from 25 to 70;
- wherein the golf ball has a coefficient of restitution of greater than about 0.81 at about 125 feet per second.
