Low deformation golf ball
View Patent ↗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.
1. 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.
2. The golf ball of claim 1 , wherein the rubber composition comprises at least about 2.2 parts per hundred of the halogenated organosulfur compound.
3. The golf ball of claim 2 , wherein the halogenated organosulfur compound is pentachlorothiophenol.
4. The golf ball of claim 3 , wherein the halogenated organosulfur compound is zinc salt of pentachlorothiophenol.
5. The golf ball of claim 1 , wherein the core has a compression of greater than about 80.
6. The golf ball of claim 1 , wherein the golf ball has a coefficient of restitution of greater than 0.75 at 160 feet per second.
7. The golf ball of claim 1 , wherein the golf ball has a coefficient of restitution of greater than 0.76 at 160 feet per second.
