Multi-layer golf ball
View Patent ↗Multi-layer golf balls having a hard, high compression center, a relatively soft intermediate layer, and a stiff outer cover layer, are provided. The outer surface hardness of the intermediate layer is less than that of both the center and the outer cover layer.
1. A golf ball consisting essentially of:
a center having a diameter of from 1.000 inches to 1.400 inches, a compression of from 40 to 55, and formed from a polybutadiene composition;
an intermediate layer having an outer surface hardness of less than 50 Shore D and formed from a polybutadiene composition having a solid, single core compression less than the compression of the center; and
a cover layer formed from a composition comprising a blend of a first ionomer, a second ionomer, and a non-ionic thermoplastic resin;
wherein the outer surface hardness of the intermediate layer is less than that of both the center and the cover layer; and
wherein the compression of a golf ball subassembly consisting of the center and the intermediate layer has a compression of 50 or less.
2. The golf ball of claim 1 , wherein the compression of the golf ball subassembly is at least 10 compression points less than the compression of the center.
3. The golf ball of claim 1 , wherein the diameter of the golf ball subassembly is 1.500 inches or greater.
4. The golf ball of claim 3 , wherein the diameter of the center is from 1.000 inches to 1.200 inches.
