OWN LABORATORY AS THE FOUNDATION OF QUALITY
ADVANCED RESEARCH
Since 2009, an important organizational unit of our company has been a modern research laboratory responsible for advanced research on raw materials processed in DRP GROUP plants.
INNOVATION
The innovative equipment of the laboratory and a team of qualified employees allow us to use a wide range of research methods aimed at determining the physicochemical properties of the processed materials with the highest accuracy.
GUARANTEE OF QUALITY
Our laboratory experts conduct research on raw materials at every stage of the processing process. This gives us full control over its course and allows us to make adjustments to recipes on an ongoing basis. Therefore, our customers are guaranteed that they receive a final product of the highest quality, with parameters perfectly suited to their needs. The confirmation of the above is the inspection certificate prepared for each delivery in accordance with DIN EN 10204 – 3.1.
Our facilities are at your disposal
For years, we have also been successfully providing polymer testing services for external clients. Thanks to the ongoing exchange of experience with universities, industry institutes and research centers, we are able to guarantee the highest quality of research and analysis while maintaining attractive prices.
