What is the difference between traditional vulcanized rubber and thermoplastic elastomer? Are they all rubber?

vulcanized rubber is called cooked rubber or rubber. The general name of rubber compound after vulcanization. After vulcanization, a three-dimensional structure is formed in the raw rubber, which has high elasticity, heat resistance, tensile strength and insolubility in organic solvents. Most rubber products are vulcanized rubber. 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 crosslinked 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 corners of the nozzle are 1% directly reused after being crushed. It not only simplifies the processing process, but also reduces the processing cost, so the thermoplastic elastomer TPE/TPR material has become the latest material to replace the traditional rubber, which is environmentally friendly, non-toxic, comfortable to the touch and beautiful in appearance, making the product more creative. Therefore, it is also a new synthetic material with more humanization and high grade, and it is also a worldwide standard environmental protection material.
