TPU, or thermoplastic polyurethane elastomer, is a block copolymer formed by the reaction of diisocyanate and polyol. Its molecular structure consists of soft and hard segments, endowing it with excellent mechanical properties. TPU features extremely high wear resistance, outstanding tensile strength, good resistance to oil and chemicals, and a wide range of adjustable hardness. It maintains flexibility at low temperatures while withstanding high-temperature processing. As an environmentally friendly material, TPU is recyclable and widely used in footwear materials, clothing accessories, cable sheaths, automotive components, and medical equipment.
