Abstract
A golf ball component and method of forming the same is disclosed herein. The golf ball component includes color concentrate additives having different colors and different material properties, such as melt flow indices or Mooney viscosities. The golf ball component features a unique pattern or visual appearance based on the inclusion of the dissimilar color concentrate additives.
Claims20
A method for forming a golf ball component, the method comprising:
- forming a composition including a base material, a first color concentrate additive having a first color, and a second color concentrate additive having a second color,
- wherein at least one of:
- (i) the first color concentrate additive has a first melt flow index, and the second color concentrate additive has a second melt flow index that is different than the first melt flow index;
- or
- (ii) the first color concentrate additive has a first Mooney viscosity, and the second color concentrate additive has a second Mooney viscosity that is different than the first Mooney viscosity, and
- forming the golf ball component from the composition, such that the first color and the second color are each separately visible in the golf ball component,
- wherein the golf ball component is a core, an intermediate layer, or a cover.

A golf ball comprising:
- a core;
- and
- at least one layer disposed about the core;
- wherein the at least one layer has a composition comprising:
- a base material comprised of polyurethane, polyurea, hybrid of polyurethane-polyurea, or ionomer,
- a first color concentrate additive having a first color, and
- a second color concentrate additive having a second color, and
- wherein the first color concentrate additive has a first melt flow index, and the second color concentrate additive has a second melt flow index that is different than the first melt flow index,
- such that the first color and the second color are each separately visible in the at least one layer, and the first and second color concentrate additives are configured to form a marbled pattern in the composition.
6 more elements
A golf ball comprising:
- a core having a composition comprising a rubber base material, a first color concentrate additive having a first color, and a second color concentrate additive having a second color;
- and
- a cover disposed about the core;
- wherein the first color concentrate additive has a first Mooney viscosity, and the second color concentrate additive has a second Mooney viscosity that is different than the first Mooney viscosity, such that the first color and the second color are each separately visible in the core, and the first and second color concentrate additives are configured to form a marbled pattern in the composition,
- wherein the rubber base material of the core has a third Mooney viscosity that is less than the first Mooney viscosity and the second Mooney viscosity,
- the first color concentrate additive is white, and the second color concentrate additive is non-white, and
- the first Mooney viscosity is at least 5% different than the second Mooney viscosity.
