TPU (thermoplastic polyurethane) is gaining increasing popularity due to its superior performance and environmentally friendly nature. Today, TPU can serve as a substitute for PVC in virtually any application where PVC is used. Moreover, TPU offers advantages that PVC simply cannot match.
TPU not only boasts excellent high tensile strength, tear resistance, toughness, and aging resistance, but it is also a well-established environmentally friendly material. Today, TPU is widely used in applications such as footwear, apparel, inflatable toys, water and underwater sports equipment, medical devices, fitness equipment, automotive seat materials, umbrellas, suitcases, and handbags.
TPU film is produced from TPU pellets through processes such as calendering, cast film extrusion, blow molding, and coating. It is currently widely used in athletic footwear for applications including sole and upper decorations, airbags, air cushions, and oil pockets.
TPU shoe materials and TPU films are seeing two emerging trends in their application to athletic footwear:
First, a trend sparked by women’s sandals involves using highly transparent TPU film—either cut directly, colored via screen printing, or laminated with fabric to create mesh-like composites—which is then thermoformed and bonded to the shoe upper, serving both functional and decorative purposes.
Second, a waterproof and breathable TPU film is laminated with shoe fabric to achieve waterproof and breathable performance.
