Differential scanning calorimetry (DSC) is a thermoanalytical technique used to determine the peak melting points and latent heat values of all PureTemp PCMs. The instrument used is called a differential scanning calorimeter. When a DSC is conducted for a PureTemp PCM, a temperature range that is 25 degrees below and 30 degrees above the peak melt of the PCM is scanned at a rate of 1°C/minute. This allows for accurate melting point and latent heat values to be obtained.
