摘要:
The present invention provides an apparatus and system for mixing castable polyurethanes for dispensing into a golf ball mold for application to a golf ball sub-assembly. The apparatus comprises a mixing block for merging together at least two polyurethane components, then a temperature control chamber to remove excess heat that is produced by the exothermic reaction resulting from the mixing of the urethane components. The mixing of the components is by passing the components through a tortuous mixing path created by a disposable static mixer element. The mixed components are dispensed into the golf ball mold by a multiple lead nozzle assembly.
摘要:
This invention is directed to golf balls including one or more foamed, microcellular materials. The invention also encompasses methods of controlling or adjusting one or more material properties or the weight distribution of a golf ball, and methods of forming golf balls including such microcellular materials.
摘要:
Golf equipment including compositions including castable formulations that have low material hardness and increased shear resistance. The compositions may be used in any layer of a golf ball including cores, intermediate layers, and covers and result in high spin rates.

摘要:
A method of making a golf ball core comprising the steps of providing a first polybutadiene pre-impregnated with at least about 50 weight percent of a first filler; providing a second polybutadiene substantially free of the first filler; providing a free radical initiator and a crosslinking agent; mixing the second polybutadiene, the free radical initiator, and the crosslinking agent with the first polybutadiene to form a polybutadiene blend; and molding the polybutadiene blend into the golf ball core.
摘要:
The disclosed invention provides a golf ball including a core and a cover of at least two layers, wherein the at least one cover layer includes an inner cover layer of at least one ionomer resin and an outer cover formed from a polymer blend including at least one grafted metallocene-catalyzed polymer and at least one ionomer neutralized with a metal cation, and optionally, a non-grafted metallocene-catalyzed polymer.
摘要:
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.
摘要:
A golf ball having a core and a cover layer disposed about the core is disclosed. The core may further include a center and an outer core layer disposed about the center. The cover layer is formed from a composition having multiple reactive and/or non-reactive ingredients. At least one of these ingredients is a hydrogenated telechelic polycarbonate polyahl having a number average molecular weight of 2,000 to 10,000.
摘要:
A golf ball comprising a core of one or more layers, a cover layer of one or more layers and a mantle layer disposed between the core and the cover. The mantle layer comprises a thermoplastic material, preferably having a hardness of greater than 60 Shore D and a Bashore resilience of greater than 34 and a vicat point of greater than 350° F.
摘要:
A golf ball comprising a core and a cover disposed about the core, wherein the core comprises a center and at least one outer core layer adjacent the center, and the cover comprises at least one inner cover layer and an outer cover layer, wherein the center has an outer diameter from about 0.375 in to about 1.4 in and deflection of greater than about 4.5 mm under a load of 100 Kg, the outer core layer has an outer diameter of from about 1.4 in to about 1.62 in, the inner cover layer has an outer diameter of greater than about 1.58 in and a material hardness of less than about 72 Shore D, and the outer cover layer has a hardness of greater than about 50 Shore D.
