Thermal Analysis

Thermal analysis refers to a suite of analytical techniques that evaluate material properties with respect to temperature. These techniques are useful for a wide range of materials and can be especially useful for studying polymeric materials.  Sample is typically held under a constant heating / cooling rate or at a constant temperature in order to study the property of interest.

Pinnacle materials laboratory offers the following thermal analysis techniques:

  • DSC (Differential Scanning Calorimetry):  We provide DSC services with the TA Instruments Q2000.  The instrument is capable of maintaining a constant heating and cooling rate.  It is also capable of performing modulated DSC (MDSC) test.  Temperature range for our DSC set up is from -80 to 400 deg-C.
  • TGA (Thermo-Gravimetric Analysis):  We provide TGA services with the TA Instruments Q500.  The instrument is capable of performing high-resolution TGA test.  Temperature range for our TGA set up is from ambient to 995 deg-C.
  • DMA (Dynamic Mechanical Analysis):  We provide DMA services with the Mettler Toledo DMA 1 and the TA Instruments Q400 EM.  Temperature range for our DMA set up is from -120 to 500 deg-C.
  • TMA (Thermo-Mechanical Analysis):  We provide TMA services with the TA Instruments Q400.  Temperature range for our TMA set up is from -120 to 900 deg-C.

TEST METHODS:  The thermal analysis services we provide range from standard test methods to user-designed methods.

MATERIAL PROPERTIES: Thermal analysis is used to determine many thermal, physical and chemical properties of materials. Here is a partial list of material properties that can be evaluated using thermal analysis techniques in our laboratory:

  • Glass transition temperature (Tg)
  • Curing
  • Decomposition, degradation or weight loss
  • Crystalline melt and crystallinity
  • Heat capacity (Cp)
  • Coefficient of thermal expansion (CTE)
  • Shrinkage
  • Softening point
