A golf ball comprising a core, a barrier layer enveloping the core, and a cover enveloping the barrier layer, wherein the barrier layer has a moisture vapor transmission rate less than that of the cover, and the barrier layer comprises a thermoplastic or thermoset composition of microparticles dispersed in a binder comprising synthetic rubbers, natural rubbers, polyolefins, styrenic polymers, or single-site catalyzed polymers, and the microparticles comprise fibers;
- whiskers;
- metal flakes;
- micaceous particles;
- or nanoparticles.
A golf ball comprising a core, a barrier layer enveloping the core, and a cover enveloping the barrier layer, wherein the barrier layer has a moisture vapor transmission rate less than that of the cover, and the barrier layer comprises a thermoplastic or thermoset composition of microparticles dispersed in a binder comprising synthetic rubbers, natural rubbers, polyolefins, styrenic polymers, or single-site catalyzed polymers, and the microparticles have a particle size of about 4 microns to about 335 microns.
A golf ball comprising a core, a barrier layer enveloping the core, and a cover enveloping the barrier layer, wherein the barrier layer comprises a thermoplastic or thermoset composition of microparticles dispersed in a binder comprising synthetic rubbers, natural rubbers, polyolefins, styrenic polymers, or single-site catalyzed polymers, and the barrier layer has a moisture vapor transmission rate of less than about 0.95 grams·mm/(m2·day) and less than that of the cover.
A golf ball comprising a core, a barrier layer enveloping the core, and a cover enveloping the barrier layer, wherein:
- the barrier layer has a moisture vapor transmission rate less than that of the cover;
- and
- the barrier layer comprises aluminum flakes comprising aluminum oxide.
A golf ball comprising:
- a core having a diameter of at least about 1.62 inches;
- a barrier layer of less than about 0.02 inches thick enveloping the core, wherein the barrier layer comprises a thermoplastic or thermoset composition of microparticles dispersed in a binder;
- and
- a cover of less than 0.03 inches thick enveloping the barrier layer, wherein the barrier layer has a moisture vapor transmission rate less than that of the cover.
A golf ball comprising a core, a barrier layer enveloping the core, and a cover enveloping the barrier layer, wherein the barrier layer has a moisture vapor transmission rate less than that of the cover, and the barrier layer comprises a thermoplastic or thermoset composition of microparticles dispersed in a binder comprising synthetic rubbers, natural rubbers, polyolefins, styrenic polymers, or single-site catalyzed polymers, wherein the barrier layer has a thickness of about 0.001 inches to 0.01 inches.
A golf ball comprising a core, a barrier layer enveloping the core, and a cover enveloping the barrier layer, wherein the barrier layer has a moisture vapor transmission rate less than that of the cover, and the barrier layer comprises a thermoplastic or thermoset composition of microparticles dispersed in a binder comprising synthetic rubbers, natural rubbers, polyolefins, styrenic polymers, or single-site catalyzed polymers, and a difference in specific gravity between the core and the barrier layer is at least 0.1 g/cm3.
