What are the factors affecting the melting point of TPU film melting? The melting points of TPU films of different materials are different. The main factors affecting the melting point of TPU film are the following three factors. Let's summarize it together!
The melting point of TPU materials can be affected by three factors:
1. Is to look at the hard segment content, the hard segment content is high, the melting point is correspondingly high;
2. The same hard segment content, high molecular weight and correspondingly high melting point;
3. The composition of the hard segment varies according to the raw material and the melting point.
The principle of melting point detection of TPU material: that is, the temperature at which TPU material is converted from solid state to molten state under constant pressure, which is the thermodynamic performance of TPU.
The above is an introduction to the factors involved in the melting point of TPU films.
