Claims20
A five-piece golf ball comprising:
- a) a core comprising a synthetic polymer selected from the group consisting of polybutadiene, polyalkenamer, thermoset polyurethanes, thermoset polyureas, thermoplastic polyurethanes, thermoplastic polyureas, unimodal ionomers, bimodal ionomers, modified unimodal ionomers, modified bimodal ionomers and any and all combinations thereof, wherein the core has a diameter of about 1.10 to about 1.50 inches, wherein the core has a specific gravity of about 1.10 to 1.40, and wherein the core has a Shore D hardness of about 30 to 80;
- b) an inner mantle layer adjacent to the core, wherein the inner mantle layer has a thickness of about .035 to about .055 inches, wherein the inner mantle layer has a specific gravity of about 0.9 to about 1.3, and wherein the inner mantle layer has material Shore D hardness of about 35.0 to about 45.0;
- c) an intermediate mantle layer disposed over the inner mantle layer, wherein the intermediate mantle layer has a thickness of about .035 to about .045 inches, wherein the intermediate mantle layer has a specific gravity of about 0.9 to about 1.3, and wherein the intermediate mantle layer has material Shore D hardness of about 40.0 to about 60.0;
- d) an outer mantle layer disposed over the intermediate mantle layer, wherein the outer mantle layer has a thickness of about .055 to about .065 inches, wherein the outer mantle layer has a specific gravity of about 0.9 to about 1.3, and wherein the outer mantle layer has material Shore D hardness of about 40.0 to about 60.0;
- e) an outer cover layer selected from the group consisting of thermoset polyurethanes, thermoset polyureas, thermoplastic polyurethanes, thermoplastic polyureas, unimodal ionomers, bimodal ionomers, modified unimodal ionomers, modified bimodal ionomers and any and all combinations thereof;
- wherein the outer cover layer has a specific gravity of about 1.0 to about 1.5, wherein the outer cover layer has a material shore D hardness of about 20.0 to about 50.0, and wherein the outer cover layer has a material flex modulus of about 5.0 to about 9.0 kilopounds per square inch (ksi);
- f) a total calculated distance of from about 310 to about 320 yards when:
- i) struck by a clubhead at a clubhead speed of 125±0.5 miles per hour (mph);
- ii) at a launch angle of 11±0.5 degrees;
- and
- iii) a spin rate of 2220±120 revolutions per minute (rpm).
