Golf ball having core composed of a highly neutralized polymer
A golf ball comprising a core composed of a fully neutralized polymer material is disclosed herein. The golf ball also preferably has multiple mantle layers and a cover.
1. A golf ball comprising:
a core composed of a fully neutralized polymer material, having a diameter ranging from 1.20 inch to 1.50 inches, and mass ranging from 25 grams to 35 grams;
an inner mantle layer disposed over the core, the inner mantle layer having a thickness ranging from 0.030 inch to 0.100 inch, the inner mantle layer composed of an ionomer material;
a first center mantle layer disposed over the inner mantle layer, the first center mantle layer having a thickness ranging from 0.030 inch to 0.050 inch, the first center mantle layer composed of a fully neutralized polymer material;
a second center mantle layer disposed over the second center mantle layer, the second center mantle layer having a thickness ranging from 0.030 inch to 0.050 inch, the second center mantle layer composed of a fully neutralized polymer material;
an outer mantle layer disposed over the second center mantle layer, the outer mantle layer having a thickness ranging from 0.030 inch to 0.050 inch, the outer mantle layer composed of a blend of ionomers; and
a cover layer disposed over the outer mantle layer, the cover having a thickness ranging from 0.025 inch to 0.040 inch, the cover composed of a thermoplastic polyurethane material;
wherein each of the mantle layers has a density substantially equal to the density of the core.
2. The golf ball according to claim 1 wherein the inner mantle is composed of a fully neutralized ionomer material.
3. The golf ball according to claim 1 wherein the golf ball has a COR of at least 0.79.
