Thermoplastic Rubber-TPR, also known as Thermoplastic Elastomer (TPE), is a material that combines the properties of rubber and thermoplastics. Thermoplastic elastomers have a variety of possible configurations. The most fundamental one is the need for at least two mutually dispersed polymer phases. At normal use temperatures, one phase is a fluid (making the temperature above its Tg-glass transition temperature). The other phase is a solid (so that the temperature is below its Tg or equal to Tg) and there is an interaction between the two phases. That is, it exhibits rubber elasticity at normal temperature, and can be plasticized and formed into a polymer material at a high temperature. It has mechanical properties and performance similar to rubber, and can be processed and recovered according to thermoplastics. It is set up between plastic and rubber. a bridge. Thus, thermoplastic elastomers can process rubber articles as quickly, efficiently, and economically as thermoplastics. In terms of processing, it is a kind of plastic; in terms of nature, it is a kind of rubber. Thermoplastic elastomers have many advantages over thermoset rubber.
