Method Of Toughening Thermoplastic Polyurethane And Articles Comprising Toughened Thermoplastic Polyurethane

摘要

A method of toughening thermoplastic polyurethane (TPU). The TPU is dipped into a urethane solution having a penetrating agent, then heated and dried for a period sufficient to toughen the surface. Also, articles such as golf balls having a toughened thermoplastic polyurethane surface. The toughened thermoplastic polyurethane surface is more scuff-resistant and has a greater strain-rate shear resistance than the TPU.
