1. A golf ball having a core and one or more cover layers encasing the core, wherein at least one of the one or more cover layers comprises a composition, the composition comprising:
a base material; and
solid glass beads whose outer surfaces have been treated to promote adhesion;
wherein the weight ratio in the composition of the base material to the solid glass beads is between 98:2 and about 95:5,
and wherein the solid glass beads are configured to alter the sound produced when the golf ball is struck without substantially altering the golf ball’s hardness and compression.
2. The golf ball of claim 1, wherein the solid glass beads are configured to increase the sound output produced when the golf ball is struck.
3. A method for preparing a golf ball layer, comprising the steps of:
preparing a composition comprising:
a base material, and
solid glass beads whose outer surfaces have been treated to promote adhesion,
wherein the weight ratio in the composition of the base material to the solid glass beads is between 98:2 and about 95:5; and
forming the composition into a golf ball layer positioned around a golf ball core, wherein the solid glass beads are configured to alter the sound produced when the golf ball is struck, without substantially altering the golf ball’s hardness and compression.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
