TPR has the following advantages: (1) It can be processed by general thermoplastic molding machines, such as injection molding, extrusion molding, blow molding, compression molding, and mold transfer molding; (2) It can be vulcanized with rubber injection molding machine, and the time can be shortened from about 20min to less than 1min; (3) It can be molded and vulcanized by a press, with fast pressing speed and short vulcanization time; (4) The wastes generated in the production process (escaping burrs and extruding waste rubber) and the final waste products can be directly returned for reuse: (5) The used TPR old products can be simply recycled and reused to reduce environmental pollution and expand the source of resource regeneration; (6) No vulcanization is required to save energy. Take the energy consumption of high-pressure hose production as an example: 188MJ/kg for rubber and 144MJ/kg for TPR, which can save more than 25% of energy; (7) The self reinforcement is great, and the formula is greatly simplified, so that the influence of the compounding agent on the polymer is greatly reduced, and the quality performance is easier to master; (8) It opens up new ways for the rubber industry and expands the application field of rubber products. The disadvantage is that the heat resistance of TPR is not as good as that of rubber, and the physical property decreases greatly with the increase of temperature, so the scope of application is limited. At the same time, the compression deformation, resilience and durability are inferior to that of rubber, and the price is often higher than that of similar rubber. However, in general, the advantages of TPR are still outstanding, while the disadvantages are constantly improving. As a new type of energy-saving and environment-friendly rubber raw material, TPR has a promising development prospect.
