The heat resistance of TPE depends not only on the material itself but is also influenced by a variety of external factors:
Formulation System: The addition of heat stabilizers and antioxidants can significantly enhance thermal aging performance.
Product Structural Design: Thin-walled products are more susceptible to deformation at high temperatures than their thick-walled counterparts.
Operating Environment: Environments characterized by alternating cycles of heat and humidity, high mechanical loads, or high friction tend to accelerate the aging of TPE.
Processing Control: The stability of temperature control during extrusion or injection molding also impacts the thermal stability of the finished product.
Therefore, when designing TPE products for high-temperature applications, it is essential to comprehensively consider four key elements-material, structure, environment, and processing-in order to select the appropriate TPE grade or to develop a customized formulation.
