The melting point of each TPU film is different. The melting point of TPU material can be affected by the following three factors:
1. The same hard segment content, high molecular weight, correspondingly high melting point;
2. Look at the content of the hard segment, the content of the hard segment is high, and the melting point is correspondingly high;
3. The composition of the hard segment depends on the raw materials and the melting point.
TPU material melting point detection principle: that is, under constant pressure, the temperature at which the TPU material is transformed from the solid state to the molten state is tested, which is the performance of the TPU thermodynamic performance.
