tpu (thermoplastic polyurethane) is a material with good thermal stability and high temperature resistance and it is used in a wide range of applications. However, the exact heat resistance varies depending on the type and formulation of the TPU, so several factors need to be considered when determining the heat resistance of a TPU.
In general, standard TPUs typically have good resistance to high temperatures and can be used at room temperature, with a temperature range typically between -30°C and 70°C. However, as technology continues to advance, modern high performance TPUs have been developed with special formulations that can be used at higher temperatures. These specially formulated TPUs can withstand higher temperatures and can typically be used in the temperature range of 100°C and above.
It is important to note that the high temperature resistance of TPUs is also influenced by other factors such as the thickness of the material, its shape and the environment in which it is used. Under high temperature conditions, TPU may soften, deform or lose some of its properties, so the choice of tpu material and process needs to be tailored to the specific needs of the application.
In addition, the high temperature resistance of TPU can also be improved by adding fillers or applying surface treatments. For example, the addition of high temperature resistant fillers or heat stabiliser treatment can improve the high temperature resistance of TPU.
In summary, TPU materials have a certain degree of high temperature resistance, but the exact temperature range depends on factors such as the type of TPU, the formulation and the application conditions. When selecting a TPU material, the specific application requirements and environmental conditions should be assessed to ensure that the material selected has adequate high temperature resistance.
