摘要： A curative blend for a thermosetting polyurethane material that allows for a polyurethane material with greater durability is disclosed herein. The curative blend is composed of 4,4′-methylenebis-(2,6-diethyl)-aniline and a second curing agent selected from the group consisting of N,N′-bis-alkyl-p-phenylenediamine, N,N′-dialkylamino-diphenylmethane with tetrapropoxylated ethylenediamine and an aliphatic diamine. A preferred polyurethane prepolymer is polytetramethylene ether glycol terminated toluene diisocyanate prepolymer. The thermosetting polyurethane is preferably utilized as a cover for a golf ball. The cover is preferably formed over a core and boundary layer.

摘要： A golf ball made by a process that prevents the cover from cracking due to thermal expansion of the core during the cover formation process. The method includes the forming a core. One or more optional boundary layers can be applied to the surface of the core. The core and any boundary layers are pre-heated such that the core and any boundary layer undergo volumetric thermal expansion. After the pre-heating, the cover of the ball is formed over the core and any boundary layer. The method of the present invention also decreases cover molding cycle times for golf balls.

摘要： A method and system for casting a thermoset layer over a golf ball precursor product is disclosed herein. The system includes multiple stations connected by a conveyor system. The thermoset flowable material is dispensed into a plurality of cavities on each of the mold halves. A plurality of golf ball precursor products are then centered and inserted into the first mold half cavities. The mold halves are mated, heated and cooled. Then, at a de-molding station, the mold halves are separated and the thermoset layered golf balls are removed from the second mold half. A preferred thermoset material is a thermoset polyurethane.
