Low deformation golf ball
View Patent ↗A golf ball including a core comprised of a partially- or fully-neutralized ionomer; a cover; and an intermediate layer disposed between the core and the cover, the intermediate layer including a base rubber and an organosulfur compound; wherein the core has a PGA compression of 60 or greater and the golf ball has a coefficient of restitution of 0.8 or greater when measured at an incoming velocity of about 125 ft/s.
1. A golf ball comprising:
a single, solid layer core comprised of a partially- or fully-neutralized ionomer, the core having a diameter of greater than 1.450 inches and a compression of greater than 90;
an outer cover layer; and
an inner cover layer disposed between the core and the outer cover layer, the inner cover layer comprising a base rubber and an organosulfur compound and having a thickness of from 0.005 inches to 0.100 inches;
wherein the golf ball has a coefficient of restitution of 0.8 or greater when measured at an incoming velocity of about 125 ft/s.
2. The golf ball of claim 1 , wherein the organosulfur compound is halogenated.
3. The golf ball of claim 1 , wherein the organosulfur compound comprises pentachlorothiophenol or the zinc or magnesium salt thereof.
4. The golf ball of claim 1 , wherein the inner cover layer has a thickness of from 0.010 inches to 0.090 inches.
5. The golf ball of claim 1 , wherein the inner cover layer has a thickness of from 0.015 inches to 0.070 inches.
6. The golf ball of claim 1 , wherein the golf ball has a coefficient of restitution of 0.81 or greater when measured at an incoming velocity of about 125 ft/s.
7. The golf ball of claim 1 , wherein the coefficient of restitution is 0.75 or greater when measured at an incoming velocity of about 160 ft/s.
8. The golf ball of claim 1 , wherein the core has a compression of greater than 100.
9. The golf ball of claim 1 , wherein the golf ball additionally comprises an intermediate cover layer.
10. The golf ball of claim 9 , wherein the combined thickness of the inner cover layer, the intermediate cover layer, and the outer cover layer is less than 0.125 inches.
11. The golf ball of claim 1 , wherein the golf ball has a coefficient of restitution of at least 0.76 when measured at an incoming velocity of 160 ft/s.
12. The golf ball of claim 11 , wherein the coefficient of restitution of the golf ball when measured at an incoming velocity of 160 ft/s is at least 95% of the coefficient of restitution of the golf ball when measured at an incoming velocity of 125 ft/s.
13. The golf ball of claim 1 , wherein the golf ball has a compression of greater than 80.
14. The golf ball of claim 1 , wherein the golf ball has a compression of greater than 90.
