Differential scanning calorimetry (DSC)

Differential scanning calorimetry (DSC)

This analysis technique consists of subjecting the sample to a controlled thermal cycle (generally scanning at temperature in a specified atmospher). Applied to polymers (thermoplastics, elastomers and thermosets), DSC reveals the thermal characteristics related to the change of physical state (fusion/crystallization and glass transition) or chemical state (crosslinking and oxidation).

Results: glass transition temperature, fusion temperature and enthalpy, crystallinity level, heat capacity and the temperatures of crosslinking, evaporation and foam expansion.

Equipment:

1. PERKIN ELMER DSC 8000 differential scanning calorimeter

  • Autosampler for loading and unloading samples
  • LN2 cooler for working down to -190 °C
  • StepScan software

2.  METTLER TOLEDO DSC 3 +

  • Autosampler
  • Measurements over a temperature range from - 150 °C to 550 °C, glass transition and melting temperatures of materials
  • Modular apparatus for performing OIT (oxidation induction time)

Associated standards:

  • NF EN ISO 11357
  • ISO 22768
  • NF T 46-050
