Background
TPU is a linear block polymer composed of (AB) n-type hard and soft segments, in which the hard and soft segments are incompatible but exist in a micro-phase separated state, and physical cross-linking points are formed at normal temperature by hydrogen bonds between urethane structures in the hard segment layer.
The TPU adopts the structure that the physical cross-linking points are connected with the flexible soft segment, so that the high polymer chains can not slide and present elasticity even when deforming. When heated, the polymer chains move after the cross-linking points are melted, and flow occurs. Therefore, TPUs possess both the physical properties of rubber, such as high elasticity, abrasion resistance, oil resistance, and the thermoplastic processability of plastics.
