We are certified in accordance with ISO 9001-2015 (call up current certificates) and, together with our partners, have state-of-the-art measuring equipment in the areas of rheological, mechanical, thermal, coloristic, chemical and electrical testing. In addition to standard tolerances, we also have the option of defining individual tolerances together with you and testing the compounds accordingly. Only products that have been properly tested within the tolerances defined in the test specifications receive approval and an acceptance test certificate. We can carry out the following tests in our laboratories:
