Thermal testing

Bramchem Testing Lab Inc. is capable of performing thermal techniques to further understand the raw materials under intense heat and pressure.

Examples of our thermal testing analyses include:

Differential Scanning Calorimetry (DSC)

Differential scanning calorimetry (DSC) is a thermoanalytical technique that measures heat flow associated with phase transitions and can provide data on both endothermic and exothermic processes. DSC has a number of sample property applications such as:

  • • glass transition temperatures
  • • oxidation heat capacities
  • • phase diagrams
  • • percent crystallinity of polymers

Thermogavimetric Analysis (TGA)

The thermogavimetric analyser (TGA) is a technique that measures the mass of a substance as a function of temperature or time as the sample heated at a constant rate in a controlled atmosphere. TGA characterizes materials in various applications.

Similar to DSC, Thermogravimetric Analysis (TGA) that are capable of identifying the following properties:

  • • Melting Points
  • • Glass Transition (TG)
  • • Crystallization Point
  • • Curing Properties
  • • Oxidation Temperatures
  • • Heat Capacity and Specific Heat
  • • Heat of Fusion and Reaction
  • • Purity • Rate of Evaporation
  • • Thermal Decomposition
  • • Thermal Stability

Melt Flow Index

Melt flow index (MFI) or melt flow rate (MFR) is a measure of the ease of flow of the melt of a thermoplastic polymer. The sample must have ability to melt to be evaluated using the MFI instrument. This testing is most popular to determine material viscosities and used for test batch-to-batch consistency.
