Thermoplastic Urethane (TPU) is a kind of elastomer that can be plasticized by heating and dissolved by solvent. It has excellent comprehensive properties such as high strength, high toughness, wear resistance, oil resistance, and is widely used in national defense, medical treatment, food and other industries. TPU plastic has excellent wear resistance, more than five times wear-resistant than natural rubber, and is one of the preferred materials for wear-resistant products.
