TPU (thermoplastic polyurethane) is a material with good thermal stability and high temperature resistance, and its temperature resistance range is usually between -30℃ and 70℃. However, with the continuous advancement of technology, modern high-performance TPU has developed special formulas that can be used at higher temperatures. These specially formulated TPUs can withstand higher temperatures and can usually be used in a temperature range of more than 100℃.
In practical applications, the high temperature resistance of TPU is also affected by other factors, such as the thickness, shape and use environment of the material. Under high temperature conditions, TPU may become soft, deform or lose certain properties, so in specific applications, it is necessary to select suitable TPU materials and processes according to actual needs.
In addition, the high temperature resistance of TPU can also be improved by adding fillers or surface treatment. For example, adding high temperature resistant fillers or treating with heat stabilizers can improve the high temperature resistance of TPU.
In summary, TPU materials have a certain high temperature resistance, but the specific temperature resistance range depends on factors such as the type, formula and application conditions of TPU. When selecting TPU materials, they should be evaluated according to specific application requirements and environmental conditions to ensure that the selected materials have sufficient high temperature resistance.
