A golf ball forming method includes forming a pair of thermoplastic hemispheres from an elastomer compound comprising an elastomer and a first free radical initiator, a second free radical initiator and a third free radical initiator, wherein the elastomer has a preliminary Crosslinking, then placing the spherical element between the hemispherical angles, and compressing and hardening the hemispherical angle at a second cross-link density around the spherical element. The method uses three different crosslinking temperatures. |
