Claims18
A golf ball, comprising:
- a dual core comprising an outer core layer disposed over an inner core layer, wherein at least one of the outer core layer or the inner core layer is formed of a composition, the composition comprising:
- a base rubber;
- and
- about 2 to 15 percent organic-free ash residue by weight of the composition, wherein the ash residue comprises about 5 percent to about 30 percent by weight of metal compounds, and wherein the metal compounds comprise (1) zinc, barium, and titanium, (2) zinc, barium, and limestone, or (3) zinc, titanium, and limestone;
- and
- a cover layer surrounding the dual core, wherein the cover layer comprises an ionomer, polyurethane, polyurea, polyurethane-urea hybrid, or copolymers and blends thereof.

A golf ball, comprising:
- a core formed of a composition, the composition comprising:
- a base rubber;
- and
- organic-free ash residue present in the composition in an amount of about 1 to 20 percent by weight of the composition, wherein the ash residue metal comprises barium, and wherein the barium is present in the ash residue in an amount of about 12 to 20 percent by weight of the ash residue;
- a cover layer;
- and
- a layer disposed between the core and the cover, wherein the layer and cover each comprises an ionomer, polyurethane, polyurea, polyurethane-urea hybrid, or copolymers and blends thereof.
4 more elements
A golf ball, comprising:
- a core formed of a composition, the composition comprising:
- a base rubber comprising polybutadiene, butyl rubber, or a combination thereof;
- and
- organic-free ash residue present in the composition in an amount of about 7 to 18 percent by weight of the composition, wherein at least one metal compound is present in an amount of about 10 percent to about 25 percent based on the total weight of the ash residue, and wherein the at least one metal compound comprises barium, limestone, or a combination thereof;
- and
- a cover layer.
