What are the most important parameters in TPU production?
2025-12-04
The key parameters for TPU are temperature, back pressure, screw shear, and tension. In particular:
• Too high a temperature will cause yellowing.
• Too low a back pressure will cause fisheyes.
• Unstable tension will lead to uneven film stretching.
• Unstable cooling will cause orange peel. We provide a material parameter library to help customers avoid pitfalls.
