A Recent blend of thermoplastic polyurethane (TPU)

Abstract Polymer blending is a well-developed manufacturing process with features of efficient production, ease of processing and good controllability. It can effectively modify and adjust the properties of polymer in order to have greater mechanical, thermal and physical properties, and thus has been commonly used to make functional polymer materials. However, the differences in polarity as well as poor interfacial between each polymer in the blend will promote the difference in polarity between the immiscible and incompatible polymers, and then the blends did not succeed as a good blend. The blending of thermoplastic polyurethane (TPU) with other polymer has been widely study with focus on the improvement of mechanical properties, wear resistance, thermal stability, toughness and other related properties. This review only focuses on the latest studies on blending TPU with other polymer, just in the range of 3 years from 2017 to 2019.
