TPEE has excellent heat resistance, the higher the hardness, the better the heat resistance; TPEE does not lose weight after continuous heating for 10h at 110~140°C, and is heated at 160°C and 180°C for 10h respectively, and the weight loss is only 0.05% and 0.1%. Therefore, the use temperature of TPEE is very high, and the short-term use temperature is higher, which can adapt to the baking temperature of the automobile production line (150-160 ° C), and its mechanical performance loss at low and low temperatures is small. TPEE is used above 120 °C, its tensile strength is much higher than TPU. In addition, TPEE also has excellent low temperature resistance, TPEE brittle point is lower than -70 °C and the lower the hardness, the better the cold resistance, most TPEE can be - Long-term use at 40 °C. Due to the balanced performance of TPEE at high and low temperatures, it has a very wide operating temperature range and can be used at -70 to 200 °C.
