Identity Testing

Infrarot Spektroskopie IR

Our Methods for Identity Testing

Identity tests are often part of automotive testing to rule out material mix-ups. This involves not only a simple polymer characterization, but also filler contents (e.g., glass fibers) or the detection of prohibited additives or auxiliary materials.

Infrared Spectroscopy (IR)

IR spectroscopy allows the identification of various polymers through spectrum comparison with databases. Simple material mix-ups can thus be reliably ruled out. However, IR spectroscopy can also be used to characterize the main components of coating systems.

Glass Fiber Content

To determine the glass fiber content, the ignition residue of a sample is determined. While organic components burn off during ignition, the inorganic glass fibers remain in the crucible. Their proportion can be determined by weighing.

To confirm the correct mixing ratio in a polymer blend (e.g., PC/ABS), additional thermal tests such as measurements of the Vicat softening temperature or the melting point can be used.
