Rare engineering applications of TPU and TPE dictate high levels of durability and flexibility. The material TPU sometimes demonstrates superior tensile strength properties alongside excellent abrasion resistance performance, enabling its use in complex applications. Some common areas where it is applicable are protective coatings, conveyor belts, and industrial wheels. Its stress and strain resistance levels are also high. It maintains material integrity. TPU is resistant to fatigue and is essential in cyclic loading areas that experience repeated stress levels. It can absorb more energy without exhibiting permanent deformation.

The used material, TPE, has elevated elastic properties and delicate substance characteristics. The substance excels at creating medical tubing components. Because of its flexible and soft factors, consumer products and automotive seals require TPE. The material readily distorts when subjected to pressure since it features weak tensile strength. TPE can absorb energy yet fails to resist pressure, resulting in lasting physical change. Therefore, processing in a harsh environment is adaptable and more straightforward. High temperatures and chemical contact lead to performance deterioration in this substance.

Case Studies of TPU vs. TPE Failures in Real-World Engineering Applications

Several TPU and TPE failure cases have occurred within an industry conveyor belt system. The application succeeds whenever high mechanical stress results in material fatigue and eventual cracking.
