Thermoplastic elastomer TPE/TPR, also known as artificial rubber or synthetic rubber. Its products not only have the excellent properties of high elasticity, aging resistance, and oil resistance of traditional cross-linked vulcanized rubber, but also have the characteristics of convenient processing and wide processing methods of ordinary plastics. It can be produced by injection molding, extrusion, blow molding, and other processing methods, and the edges and corners of the nozzle can be directly reused after being crushed. By simplifying the processing process and reducing processing costs, thermoplastic elastomer TPE/TPR materials have become a new material that replaces traditional rubber. They are environmentally friendly, non-toxic, comfortable to touch, and have a beautiful appearance, making products more creative. Therefore, it is also a new type of synthetic material with more humanization and high grade, and is also a world-class standard environmental protection material.
