Differential Scanning Calorimetry (DSC) and Modulated DSC

Differential scanning calorimetry (DSC) is among the most commonly used technologies to determine material thermal events such as:

  • Glass transition temperature (Tg)
  • Melting point (Tm)
  • Crystallization temperature
  • Heat of fusion
  • Cure kinetics
  • Degree of cure

PDI also has the capability of Modulated DSC, which provides even better resolution and sensitivity. The method reveals subtle and overlap thermal events that are not separable through the standard DSC method.

Thermal Conductivity and Diffusivity

The laser flash method is an advanced testing procedure to measure thermal conductivity. With this method, PDI scientists are able to determine thermal conductivity from room temperature up to 200°C (392°F).

Thermomechanical Analysis (TMA)

TMA measures the change of a dimension or a mechanical property as a function of temperature. Our scientists can determine the coefficient of thermal expansion in both machine and cross direction.

Thermogravimetric Analysis (TGA)

Thermogravimetric analysis (TGA) measures the change of weight through a heating process. It is a very useful tool to determine thermal stability, degradation and decomposition temperature and kinetics, organic and inorganic content, and volatile content.

Karl Fischer Titration (Moisture Analysis)

The Karl Fischer Titration method provides high precision and accuracy. Thanks to its great selectivity for water, it is not easily affected by other volatile components in a material.
