Température de transition vitreuse (T _g ) ; glass transition temperature

Temperature characteristic of the reversible transition from the glassy to the rubbery state. This phenomenon affects the material's mechanical properties, and is measured by differential scanning calorimetry (DSC).

Cône calorimètre; cone calorimeter

Instrument used to study the fire behavior of small samples, with a surface area of 100 x 100 mm ² . It provides information on the heat output of burning polymers as a function of time when subjected to radiative flux.
