The optical (digital) microscope (OM) observation is to determine the microstructure of the material. There are no standards in microscopic observations. The aim of the observation is to compare the microstructure of the observed material with the progress of the ageing process using different magnifications.
Tests are performed on samples in the solid state with dimensions of 40mm x 40mm x 3mm. In OM there are no dimensional restrictions. Optical (digital) microscope - Keyence VHX-7000 is used for the tests.
As part of the testing of the PM&VL7 research line, Rothoblaas membranes and tapes, Flex&Robust connections, injections and layers were examined before, during and after ageing.
