# Laboratory analysis of thermoplastic polymers

## You want to carry out an analysis of thermoplastic polymers

### Thermoplastic polymers in a nutshell

Firstly, a thermoplastic [polymer](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/laboratory-material-testing/laboratory-polymer-characterization/) is a polymer that has the property of softening when heated, but which becomes hard again on cooling. The softened state thus allows **mechanical deformation**, which is frozen by cooling.

The **thermoplasticity of** thermoplastic polymers is **reversible**, unlike thermoset polymers which, once cooled, can no longer change shape.

### Why carry out an analysis of thermoplastic polymers?

Determining the properties of thermoplastic polymers is essential in **production** process or **finished product control** issues. A complete understanding of the properties of your thermoplastic polymers is also necessary to anticipate their development in the **environment in which they will be used**.

The **degree of polymerisation** (proportional to**molar mass**) of a thermoplastic polymer determines its **mechanical and thermal properties**.

In addition, **crystallinity**, **cross-linking** and **glass transition and melting temperatures** also play a part in determining the properties of a thermoplastic polymer.

So the expertise of a laboratory skilled in polymer analysis is needed to determine all these properties.
