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) 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

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 (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.
