Thermoplastic temperature curve
Webb12 sep. 2024 · The dynamic mechanical thermal analysis thus provides an alternative way to determine the glass transition temperature. Because it is actually measuring a different physical phenomenon than differential scanning calorimetry, the Tg obtained from a DMTA experiment may not agree exactly with one obtained from a DSC experiment. WebbThe kinetic theory of gases allows accurate calculation of the temperature-variation of gaseous viscosity. The theoretical basis of the kinetic theory is given by the Boltzmann …
