Abstract
A golf ball component, such as a golf ball cover layer, formed from a reaction injection molded polyurethane, polyurea or polyurethane/polyurea is disclosed. The cover layer may be relatively thin (for example, 0.075 or less, preferably 0.050 inches or less, more preferably less than 0.040 inches, even more preferably less than 0.030 inches). The golf ball component is produced from a fast reacting aromatic polyurethane composition that is PTMEG based.
