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)
- Decomposition, degradation or weight loss
- Crystalline melt and crystallinity
- Heat capacity (Cp)
- Coefficient of thermal expansion (CTE)
- Softening point
