Estimating the term…
A golf ball with at least one moisture vapor barrier layer is disclosed. In accordance to one aspect of the invention, the moisture vapor barrier layer may comprise nano particles, flaked glass, flaked metals or ceramic particles to increase the layer's resistance to the transmission of moisture through the layer. In accordance to another aspect of the invention, the moisture vapor barrier layer may comprise a soft, high specific gravity layer to increase the moment of inertia of the golf ball. In accordance to another aspect of the invention, the moisture vapor barrier layer may comprise a multi-layer thermoplastic film. In accordance to another aspect of the invention, the moisture vapor barrier layer may be positioned adjacent to a wound layer such that the moisture vapor barrier layer penetrates into the interstitial spaces in the wound layer to minimize the transmission of moisture vapor through the wound layer. In accordance to another aspect of the invention, the moisture vapor barrier layer is made by a single component casting method. This method preferably uses a single component that is stable at a predetermined low temperature, and preferably becomes deblocked and reacts at a predetermined higher temperature to form the moisture vapor barrier layer or other components of the golf ball. Alternatively, the moisture vapor barrier layer can be made by a two-component castable method, spraying, dipping, preformed semi-cured shells, compression molding, injection molding, reaction injection molding or other methods.
A golf ball comprising a core, an intermediate layer and a cover, wherein the intermediate layer has a moisture vapor transmission rate that is lower than that of the cover and wherein the specific gravity of the intermediate layer is greater than that of the core.
A golf ball comprising a core, an intermediate layer and a cover, wherein the intermediate layer has a moisture vapor transmission rate that is lower than that of the cover and wherein a primary ingredient of the intermediate layer is made from a material selected from the group consisting of polybutadiene, natural rubber, butyl-based rubber, acrylics, trans polyisoprene, neoprene, chlorinated polyethylene, and balata.
A golf ball comprising a core, an intermediate layer and a cover, wherein the intermediate layer has a moisture vapor transmission rate that is lower than that of the cover and wherein the intermediate layer is made from a material selected from the group consisting of multi-layer thermoplastic films, blends of ionomers, polyvinyl alcohol copolymer and polyamides, and dispersions of acid salts of polyetheramines.
A golf ball comprising a core, an intermediate layer and a cover, wherein the intermediate layer has a moisture vapor transmission rate that is lower than that of the cover and wherein the intermediate layer comprises micro particles.
A golf ball comprising a core, an intermediate layer and a cover, wherein the intermediate layer has a moisture vapor transmission rate that is lower than that of the cover and wherein the intermediate layer comprises a rubber-based primary ingredient, a cross-linking agent, a free radical source and fillers.
A golf ball comprising a core, an intermediate layer and a cover, wherein the core comprises a first wound layer and a second wound layer and the first and second wound layers are made from different threads, and wherein the intermediate layer has a moisture vapor transmission rate that is lower than that of the cover.
A golf ball comprising a core, an intermediate layer and a cover, wherein the intermediate layer has a moisture vapor transmission rate that is lower than that of the cover and wherein the intermediate layer and the core have a Shore D hardness of less than about 50.
A method of casting a portion of a golf ball comprising the steps of:
