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:
a single, solid layer innermost core having a Shore C hardness of greater than 70 and a flexural modulus of from 80,000 psi to 200,000 psi;
a cover; and
a intermediate layer disposed between the innermost core and the cover, wherein the intermediate layer comprises a rubber composition containing a halogenated organosulfur compound and has a thickness of from 0.001 inches to 0.100 inches, a Shore C hardness of from 25 to 70, and a flexural modulus of from 500 psi to 25,000 psi;
and wherein the core and the intermediate layer have a diameter of greater than 1.50 inches and a compression of greater than about 80.
2. The golf ball of claim 1 , wherein the core and the intermediate layer have a compression of greater than about 90.
3. The golf ball of claim 1 , wherein the golf ball has a coefficient of restitution of at least about 0.81 at about 125 feet per second.
4. The golf ball of claim 1 , wherein the golf ball has a coefficient of restitution of at least about 0.76 at about 160 feet per second.
5. The golf ball of claim 1 , wherein the core has a compression of greater than about 70.
6. The golf ball of claim 1 , wherein the core has a compression of greater than about 80.
7. The golf ball of claim 1 , wherein the thickness of the intermediate layer is from about 0.010 inches to about 0.050 inches.
8. The golf ball of claim 1 , wherein the thickness of the intermediate layer is from about 0.015 inches to about 0.035 inches.
9. The golf ball of claim 1 , wherein the innermost core comprises a fiber- or filler-reinforced polymer.
