Abstract
The present disclosure provides a resin composition for a golf ball cover. The resin composition includes a thermoplastic polyurethane resin including 55 to 70 parts by weight of a polyol, 30 to 40 parts by weight of an isocyanate, and 0.2 to 0.4 parts by weight of a polysiloxane. The polysiloxane includes at least one hydroxyl group or a carboxyl group in the terminal alkyl group. The polyol and the isocyanate constitute a silicone-free thermoplastic polyurethane resin, and the polysiloxane and the isocyanate constitute a thermoplastic polyurethane resin that includes silicone in the main chain, thereby improving the scuff resistance and slip property required for a golf ball cover.
