What is the temperature resistance range of TPU waterproof membrane?

TPU (thermoplastic polyurethane) waterproofing membrane is a material widely used in outdoor sportswear, mountaineering equipment, raincoats and other fields, and is favored for its excellent waterproofness and breathability. The temperature resistance of TPU materials is usually between -40°C and 80°C. Some high-performance TPU membranes are even able to withstand higher temperatures, but in general, environments above 80°C may affect their physical properties, including water resistance and breathability.

The temperature resistance of TPU film has a lot to do with its preparation process and specific application. For example, TPU membranes may soften or lose their shape in high-temperature environments, so it is necessary to consider the use scenarios and environmental conditions when designing and using TPU waterproofing membrane products. In addition, as a polymer material, the temperature resistance of TPU is usually affected by the time factor, and long-term exposure to high temperatures may lead to aging and performance degradation of the material.

Therefore, when choosing TPU waterproof membrane products, it is recommended to carefully check the temperature resistance range in the product manual, and choose the appropriate product according to the actual use needs to ensure that it can maintain a good waterproof effect and service life in various environments. At the same time, regular maintenance and inspection of the equipment can effectively extend the service life of the TPU film and ensure the comfort and safety of users in outdoor activities.
