Performance analysis and application of thermoplastic elastomers (I)


in recent 30 years, thermoplastic elastomers, as the third generation of rubber, have achieved rapid development in the world of double space full-automatic electronic tensile testing machines. Now, the output of thermoplastic elastomer has already surpassed that of the second generation of liquid rubber, and has become another new material in today's rubber industry

thermoplastic elastic and introduced to Elbegdorj that the Chinese entourage has the physical and mechanical properties of vulcanized rubber and the processing properties of soft plastic. Because there is no need to go through thermal vulcanization like rubber, the final product can be easily made by using simple plastic processing machinery. This feature shortens the production process of the rubber industry by 1/4, saves energy consumption by 25% - 40%, and improves efficiency times. It can be called another material and process technology revolution in the rubber industry

thermoplastic elastomer is a new polymer material between rubber and resin. It can not only replace part of rubber, but also modify plastics. Thermoplastic elastomer has the dual properties and broad characteristics of rubber and plastic, which makes it widely used in the rubber industry to manufacture rubber shoes, tapes and other daily-use products, as well as various industrial supplies such as rubber hoses, tapes, strips, plates, parts and adhesives. At the same time, thermoplastic elastomer can also replace rubber and be widely used in the modification of general thermoplastic resins such as PVC, PE, PP, PS and even engineering plastics such as PU, PA, CA, which has also brought a new situation to the plastic industry

1 types and performance characteristics of thermoplastic elastomer

thermoplastic elastomer (TPE) can be summarized as general TPE and engineering TPE. At present, it has developed to more than 30 varieties in 10 categories, as shown in Table 1. From the earliest discovery of polyurethane TPE by Bayer in Germany in 1938, the development of styrene butadiene styrene block polymer TPE by Phillips and shell in the United States in 1963 and 1965, to the mass production of olefin TPE in the United States, Europe and Japan in the 1970s, continuous technological innovation and the emergence of new TPE varieties have formed a huge system of TPE today, which has greatly advanced the combination and marriage of rubber industry and plastic industry
