Services
The laboratory conducts physical and chemical testing of polymeric materials, as well as technological tests. For details on the ordering and cost of tests, it is necessary to contact the head of the laboratory andres.krumme@taltech.ee. The laboratory conducts the tests within the best possible limits but is not accredited for these methods and the results are therefore of an indicative nature.
