摘要 |
A golf ball including a core and a cover including a thermoplastic inner cover layer having a material hardness of 60 to 80 Shore D; a thermoset outer cover layer comprising a castable polyurea and having a material hardness of 20 to 60 Shore D; and a thermoset intermediate cover layer disposed between the inner and outer cover layers and having a hardness substantially the same as the inner cover layer hardness and greater than the outer cover layer hardness. The inner cover includes one or more high- or low-acid ionomers and, optionally, a maleic anhydride modified polyolefin.
