This review article provides an exhaustive survey on experimental investigations regarding the thermal stability. Low temperature performance can be a very im-portant characteristic of an elastomeric compound. They are distinguished from semi-crystalline plastics by their special molecular structure, which consists of rigid, rod-like macromolecules that are ordered in the melt phase to form. Thermoplastic polyurethanes (TPUs) offer exciting possibilities for meeting the manufacturing challenges of a fast-changing world. from shoes, seals and films to filters, conveyor belts and cables. coating, injection molding, extrusion, film and compounding application requirements.
