Abstract

A golf ball including a core and a cover layer, wherein the golf ball has a lift to weight ratio greater than about 1.7 at a Reynolds number of about 207,000 and a non-dimensional spin ratio of about 0.095, a COR of 0.790 or less, and a weight of about 1.39 to 1.62 oz; and wherein the cover layer has an outer surface including dimples covering 55% to 75% of the outer surface.

Claims (23)

1. A golf ball comprising:

a core; and

a cover layer;

wherein the golf ball has a lift to weight ratio greater than about 1.7 at a Reynolds number of about 207,000 and a non-dimensional spin ratio of about 0.095, a COR of 0.790 or less, and a weight of about 1.39 to 1.62 oz; and

wherein the cover layer has an outer surface comprising dimples covering 55% to 75% of the outer surface.

2. The golf ball of claim 1 , wherein the core comprises polybutadiene, butyl rubber, a co-reaction agent, or a peroxide.

3. The golf ball of claim 2 , wherein the butyl rubber is halogenated.

4. The golf ball of claim 1 , wherein the COR is about 0.550 to 0.785.

5. The golf ball of claim 4 , wherein the COR is about 0.600 to 0.780.

6. The golf ball of claim 1 , wherein the weight is about 1.45 to 1.60 oz.

7. The golf ball of claim 6 , wherein the weight is about 1.45 to 1.58 oz.

8. The golf ball of claim 1 , wherein the golf ball has an outer diameter of about 1.675 in to 1.695 in.

9. The golf ball of claim 1 , wherein the golf ball has a drag-to-weight ratio that is 2.4 or greater at a Reynolds number of about 207,000 and a non-dimensional spin ratio of about 0.095.

10. The golf ball of claim 9 , wherein the golf ball has a drag-to-weight ratio that is 2.7 or greater at a Reynolds number of about 207,000 and a non-dimensional spin ratio of about 0.095.

11. The golf ball of claim 10 , wherein the golf ball has a drag-to-weight ratio that is 3.0 or greater at a Reynolds number of about 207,000 and a non-dimensional spin ratio of about 0.095.

12. The golf bail of claim 1 , wherein the dimple coverage is 65% to 75%.

13. The golf ball of claim 1 , wherein the cover layer comprises an ionomer, non ionomer, or polyurethane.

14. The golf ball of claim 1 , wherein the golf ball comprises a casing or inner cover layer disposed between the core and the cover.

15. The golf ball of claim 14 , wherein the inner cover or casing layer comprises an ionomer and the cover comprises a polyurethane.

16. The golf ball of claim 1 , wherein the core comprises a polybutadiene, a co-reaction agent, a peroxide, and at least one of a butyl rubber, a halogenated butyl rubber, a butyl rubber copolymer, a sulfonated butyl rubber, a polyisobutylene, an ethylene propylene diene monomer rubber, a copolymer of isobutylene and methylstyrene, or a styrene butadiene rubber.

17. The golf ball of claim 1 , wherein the cover layer comprises a urethane.

18. The golf ball of claim 1 , wherein the lift to weight ratio is greater than about 1.9 at a Reynolds number of about 207,000 and a non-dimensional spin ratio of about 0.095.

19. The golf ball of claim 18 , wherein the lift to weight ratio is greater than about 2.1 at a Reynolds number of about 207,000 and a non-dimensional spin ratio of about 0.095.
