Abstract
A golf ball having a cover material made from a polyurethane or polyurethane/urea hybrid composition is provided. The polyurethane or polyurethane/urea composition is produced by the reaction of an isocyanate blend having an average NCO functionality in the range of 2.05 to 2.35, a polyamine compound, and amine or hydroxyl chain-extender. The resulting cover material has many advantages including improved thermal-stability, durability, toughness, and cut/tear-resistance. The preferred isocyanates in the blend include isophorone diisocyanate ('IPDI'); 1,6-hexamethylene diisocyanate ('HDI'); 4,4'-dicyclohexylmethane diisocyanate (“HMDI”); 4,4′-diphenylmethane diisocyanate (4,4′MDI); toluene diisocyanate (“TDI”); and homopolymers and copolymers thereof.
