Golf ball with high coefficient of restitution
View Patent ↗The present invention is a golf ball that has a coefficient of restitution at 143 feet per second that is greater than 0.8015, and an USGA initial velocity less than 255.0 feet per second. The golf ball is preferably a solid three-piece golf ball with a thermosetting polyurethane cover, an ionomer blend intermediate layer and a polybutadiene core.
1. A golf ball comprising:
a solid core composed of a polybutadiene blend, having a PGA compression ranging from 100 points to 110 points, and having a diameter ranging from 1.35 inches to 1.64 inches, the core having a mass ranging from about 32 grams to about 40 grams;
an intermediate layer disposed above the core, the intermediate layer composed of an ionomer material, having a Shore D hardness ranging from 50 points to 75 points as measured on the curved surface of the intermediate layer, and the intermediate layer having a thickness ranging from 0.040 inch to 0.09 inch; and
a cover disposed over the intermediate layer, the cover composed of a polyurethane material, the cover having a thickness ranging from 0.020 inch to 0.0375 inch;
wherein the golf ball has a coefficient of restitution or 143 feet per second greater than 0.7964, and an USGA initial velocity of less than 255.0 feet per second, and the golf ball has a ball Shore D hardness ranging from 50 points to 75 points as measured on the surface of the golf ball.
2. The golf ball according to claim 1 wherein the cover has a thickness ranging from 0.025 inch to 0.035 inch.
3. The golf ball according to claim 1 wherein the cover has a thickness of 0.030 inch.
4. The golf ball according to claim 1 wherein the core has a PGA compression of 110 points.
5. The golf ball according to claim 1 wherein the golf ball has a coefficient of restitution at 143 feet per second greater than 0.8150.
