TPEE has the elasticity of rubber and the strength of engineering plastics, it has better processing performance and longer service life than rubber; abstract to engineering plastics, the same characteristics of high strength, flexibility and dynamic mechanical performance is better.TPEE has excellent heat resistance,the higher the hardness, the better the heat resistance; it can be heated continuously at 110 to140 ℃ 10h basic weightless . When heated at 160 ℃ and 180 ℃ for 10h, the weight loss is only 0.05% and 0.1%.So TPEE has a very high temperature for short-term use can adapt to the paint temperature (150 to160 ℃) on the automobile production line, and it has small loss of mechanical performance at high and low temperatures. Its tensile strength is much higher than TPU when the temperature above 120℃. In addition, TPEE also has low temperature resistance. The brittle point of TPEE is lower than -70 ℃ and the lower the hardness, the better the cold resistance. Most TPEE can be use
