tpu film quality identification method

the quality of tpu film can be distinguished from the following aspects:

1. transparency: the higher the transparency of the tpu film, the better the quality. the quality can be judged by comparing the transparency of tpu films of different brands with the same thickness. ⒉thickness: the more uniform the thickness of the tpu film, the better the quality. you can use a thickness gauge to test whether the thickness at different locations is consistent.

3. tensile strength: the higher the tensile strength of the tpu film, the better the quality. the tensile strength of different brands of tpu films can be tested through laboratory tensile tests. 4. heat resistance: the better the heat resistance of the tpu film, the better the quality. the heat resistance of different brands of tpu films can be tested through laboratory thermal stability tests. 5. anti-yellowing: the better the tpu film’s anti-yellowing, the better the quality. the yellowing resistance of different brands of tpu films can be tested through laboratory yellowing tests. in short, the quality of tpu film needs to be comprehensively evaluated from multiple aspects.
