Polymers and Composites

At Centro Tecnológico Riojano, we conduct different tests in the research of innovative applications, as well as to verify the compliance of the requirements of the materials in both their nature and their final intended use.


Qualitative determination of components by means fo Thermogravimetric analysis

  • Qualitative determination of components (polymers and other organic compounds) by means of Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy (FTIR-ATR) and by means of transmission
  • Determination of the glass transmission temperature (Tg) of materials
  • Thermal analysis by means of DTA and DSC
  • Ash content in polymers and rubber mixtures
  • Identification of polymers, fillers and plasticisers in polymer compounds by means of Infrared spectroscopy
