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:
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 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.
摘要:
A nozzle for an injection molding machine is disclosed. The nozzle includes a nozzle body, an inner nozzle, and an outer nozzle. The nozzle defines two independent flow paths therethrough. The nozzle can simultaneously discharge two materials. A method of using the nozzle and a resulting golf ball product are also disclosed.

摘要:
The present invention is directed towards a multi-layered golf ball, at least the inner cover having multiple layers formed by a sandwich injection molding process, wherein each multi-layered cover comprises an inner layer and an outer layer of a first material and an intermediate layer therebetween of a second material. The materials having different properties. An embodiment of the invention includes both covers being multi-layered formed by the sandwich injection molding process.
摘要:
A golf ball having a diameter and comprising a fluid mass at the center of the ball, a first, solid, non-wound layer surrounding the fluid mass comprised of a non-elastic polymer material selected from the group of thermoplastic material, metal, and plastic, and having an inner diameter in the range of 30 to 70% of the ball diameter; a second, solid, non-wound layer surrounding the first mantle layer comprising an elastomeric polymer material selected from the group of thermoset rubber material and thermoplastic clastomeric material having an outer diameter in the range of 80 to 98% of the ball diameter, a hardness of less than about 65 Shore D, and a compression of about 80 or greater; and a cover surrounding the second layer.
