Laboratory

Since 1972 we have our laboratory in Kerpen, Germany

Polymer testing

To develop a new material or to further develop or modify existing materials, a large number of laboratory tests are required. Thanks to our extensive laboratory equipment and decades of experience, we are able to carry out all relevant tests ourselves and use the data obtained as basis for further developments.

We provide this knowledge and the following tests/analysis, that we can carry out with our laboratory equipment, as a fee-based service to our customers: 

  • mechanical, tribological and electrical tests
  • thermal analysis
  • material analysis
  • test bench tests (plain bearings, spindle nuts, friction &
    wear, etc.)
  • damage analysis
  • customised tests
  • compound development & production
  • manufacturing of samples
  • material optimisation

Materials analysis

Determination of the material on unknown samples

By combining several individual tests, we can determine on unknown plastic material samples, the base polymer & which components and fillers are contained and in what proportions.

The following analysis methods are usually sufficient for a material analysis:

  • FT-IR to determining base polymers
  • DSC to determining the melting temperature and the glass transition temperature
  • TGA to determining the proportions of components and
    to track down fillers
  • possibly the series of experiments is supplemented by microscopic examinations.

Send us a material sample – we will then tell you which material it is and if you wish it, we can recommend a suitable material alternative from our product range.

You will receive a detailed test report from us with the results and evaluations of all individual tests.
