Method and system for utilizing radio-opaque fillers in multiple layers of golf balls
A golf ball comprising layers that have from 0.05% to 70% by weight of a radio-opaque filler, and wherein the concentration of the radio-opaque filler is measurably different in each layer is disclosed herein. The radio-opaque filler is preferably a compound based on barium, bismuth, tungsten, iodine, or reduced iron.
1. A golf ball comprising:
a center core comprising polybutadiene;
an outer core disposed over the center core;
an inner mantle layer disposed over the outer core, the inner mantle layer having a thickness ranging from 0.03 inch to 0.09 inch, the inner mantle layer composed of an ionomer material, the inner mantle layer material having a plaque Shore D hardness ranging from 34 to 55;
an outer mantle layer disposed over the inner mantle layer, the outer mantle layer having a thickness ranging from 0.025 inch to 0.050 inch;
and
a cover layer, wherein the cover layer is disposed over the outer mantle layer, the cover layer has a thickness ranging from 0.025 inch to 0.040 inch;
wherein each of the center core, the outer core, the inner mantle layer, the outer mantle layer and the cover layer comprises from 0.05% to 70% by weight of a radio-opaque filler, and wherein each of the center core, the outer core, the inner mantle layer, the outer mantle layer and the cover layer has a concentration of the radio-opaque filler that is measurably different than a concentration of radio-opaque filler of any other layer.
2. A golf ball comprising:
a center core comprising polybutadiene;
an outer core disposed over the center core;
an inner mantle layer disposed over the outer core, the inner mantle layer having a thickness ranging from 0.030 inch to 0.090 inch, the inner mantle layer material having a plaque Shore D hardness ranging from 30 to 50;
an outer mantle layer disposed over the inner mantle layer, the outer mantle layer having a thickness ranging from 0.025 inch to 0.070 inch, the outer mantle layer material having a plaque Shore D hardness ranging from 50 to 71, wherein the inner mantle is thicker than the outer mantle, and the outer mantle is harder than the inner mantle; and
a cover layer, wherein the cover layer is disposed over the outer mantle layer;
wherein each of the center core, the outer core, the inner mantle layer, the outer mantle layer and the cover layer comprises from 0.05% to 70% by weight of a radio-opaque filler, and wherein each of the center core, the outer core, the inner mantle layer, the outer mantle layer and the cover layer has a concentration of the radio-opaque filler that is measurably different than a concentration of radio-opaque filler of any other layer.
3. A golf ball comprising:
a center core comprising polybutadiene;
an outer core disposed over the center core;
an inner mantle layer disposed over the outer core, the inner mantle layer having a thickness ranging from 0.070 inch to 0.090 inch, the inner mantle layer composed of an ionomer material, the inner mantle layer material having a plaque Shore D hardness ranging from 36 to 44;
an outer mantle layer disposed over the inner mantle layer, the outer mantle layer having a thickness ranging from 0.025 inch to 0.040 inch, the outer mantle layer composed of an ionomer material, the outer mantle layer material having a plaque Shore D hardness ranging from 65 to 71; and
a cover layer, wherein the cover layer is disposed over the outer mantle layer, the cover layer having a thickness ranging from 0.025 inch to 0.040 inch;
wherein each of the center core, the outer core, the inner mantle layer, the outer mantle layer and the cover layer comprises from 0.05% to 70% by weight of a radio-opaque filler, and wherein each of the center core, the outer core, the inner mantle layer, the outer mantle layer and the cover layer has a concentration of the radio-opaque filler that is measurably different than a concentration of radio-opaque filler of any other layer.
