Preparation and performance characteristics study of thermoplastic polyurethane elastomer (TPU) for basketball shoe soles

Thermoplastic Polyurethane Elastomer (TPU) materials have found extensive applications in the preparation of basketball shoe soles, owing to their excellent elasticity, lightweight properties, and durability. However, TPU materials still face challenges related to breathability, temperature sensitivity, and weather resistance, necessitating further research and improvement. This paper primarily investigates the advancements in E-TPU materials with high rebound foam particles tailored for basketball shoe sole applications. It emphasizes the factors influencing their performance and presents performance control methods from the perspectives of synthesis, molding, and usage. This research provides innovative approaches and methodologies for basketball shoe sole design.
