Thermoplastic elastomers combine the good process ability of plastics and the mechanical properties of elastomers, which are important for designers of components. These materials are made up of end-blocked thermoplastics and middle-elastic blocks. So according to their structure and behavior, these materials belong to a class that is between plastics (thermoplastics) and robber (elastomers) and gradually created a class of materials for themselves.
In addition to enhancing the performance of the components, with the ability to achieve a wide range of properties, these materials also provide a lot of economic benefits to polymer manufacturers. TPE and TPVs behave like a plastic when heated, and also behave like an elastic as a result of cooling. In elastomers, this behavior is related to the presence of cross-links. While in TPEs and TPVs, this phenomenon is the result of physical bonds, in which any change in the behavior that results from heat will be reversible. In fact, due to the application of heat or shear force, these materials will flow freely and become moldable, and by cooling the materials, there will be physical connections that fix the elastic blocks in a three-dimensional structure. As a result of this, while TPE and TPVs exhibit elastic properties, they can be freely flowable and formable, like thermoplastics.
