摘要:
Polyisobutylene-based compositions suitable for making golf balls are provided. The amine-terminated polyisobutylene may be reacted with an isocyanate and amine-terminated curing agent to produce a polyurea composition that may be used as a cover material and/or intermediate casing layer. The resulting ball has improved weatherability. In one version, the golf ball includes a polyurea casing layer and polyurea cover. In a second version, the golf ball includes an ionomer casing layer and polyurea cover. In yet another version, the golf ball includes a polyurea casing layer and ionomer cover.
摘要:
A multi-layered golf ball having an inner core, at least one intermediate layer, and outer cover is provided. The intermediate layer is made from a polyurea composition containing ultra-high molecular weight polyethylene powder particulate dispersed therein. The intermediate layer provides the ball with advantageous properties including improved durability, toughness, hardness, and impact-resistance.
摘要:
A golf ball comprising a core, a cover and at least on intermediate layer therebetween. The intermediate layer includes pigment which contributes to the color or appearance of the ball and the cover is at least partially transparent such that the intermediate layer is at least partially visible. The cover is also comprised of an optical enhancer.
摘要:
Golf balls having a hard outer skin produced from a material that includes crosslinks in both the hard and soft segments of the polymer backbone that improve the crosslink density. Compositions formed from polyurethane and/or polyurea prepolymers that are first cured with a curative blend including an isocyanate-reactive component to crosslink the hard segment and then exposed to a free radical initiator and radiation to crosslink the soft segments are used in an outer layer of a golf ball, a unitary golf ball, or other golf ball constructions.
摘要:
Compositions for golf balls that include polyurethane and/or polyurea linkages and that are crosslinked in the soft segments of the polymer backbone. In particular, the compositions of the invention, which are based on a polyurethane and/or polyurea, have improved crosslink density and hardness from the crosslinking between the soft, unsaturated segments of the polymer backbone. The curative blend includes at least one isocyanate-reactive component and a free radical initiator.
摘要:
The present invention is directed a golf ball having at least a transparent or translucent cover and a core. The golf ball may also comprise an intermediate layer disposed between the core and the cover. The transparent or translucent cover may comprise a plurality of dimples on its surface as well as depressions other than dimples, such as stripes, text, or logos. Both the cover and the core may comprise an amount of dye or dyes. The cover may additionally comprise an amount of reflective particulates. The core may include a plurality of projections and/or depressions on its surface to provide more surface area for the adhesion of the cover to the core.
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:
Multi-layer golf balls having a hard, high compression center, a relatively soft intermediate layer, and a stiff outer cover layer, are provided. The outer surface hardness of the intermediate layer is less than that of both the center and the outer cover layer.

摘要:
Compositions for golf balls that are formed from the reaction product of an isocyanate-containing component and an amine-terminated component having an unsaturated backbone, which is cured with a curing agent. In particular, the compositions of the invention may be formed from a prepolymer having urea linkages and at least one carbon-carbon double bond in the backbone that is cured with an amine-terminated component resulting in golf balls having weight gain comparable to ionomers and less loss of COR as compared to ionomers and conventional polyurethanes after submersion in water.
