Bonding properties and crystallization kinetics of thermoplastic polyurethane adhesive

ABSTRACT The advantages of heterophasic thermoplastic polyurethanes (TPUs), such as their phase behavior and mechanical properties, make these materials an important class of adhesives. Whereas the amorphous phase contributes to good adhesion properties, the crystalline phase is responsible for the cohesive force of TPU adhesives. This work investigates the performance of a polyester based TPU and its potential for being applied as adhesive in the shoe industry. The TPU was formulated with three different additives. The crystallization kinetics of the TPU was evaluated by Differential Scanning...
