Our Capabilities
Thermal Analysis
A portfolio of complementary techniques used to measure the physical properties of materials versus temperature, time and environment.
Methods
- Differential Scanning Calorimetry (DSC)
- Thermomechanical Analysis (TMA)
- Thermogravimetric Analysis (TGA)
- Dynamic Mechanical Analysis (DMTA)
Applications of Thermal Analysis
- Evaluating melting points, glass transition, crystallinity, thermal history, nucleation, enthalpy of fusion or re-crystallisation, specific heat capacity
- Measurement of coefficient of thermal expansion, shrinkage data, anisotropy due to fillers/reinforcing materials, softening temperatures
- Determination of thermal stability / thermal oxidative stability, thermal transitions, solvent loss, water / filler content, organic / inorganic ratios
- Characterisation of stiffness and damping properties, molecular phase interactions by mechanical loss.
The MSG advantage
- Identification of morphological changes in a specimen, by DSC
- -70°C to 550°C, option of MDSC if required (-70 to 400°C)
- Measurement of dimensional change along one axis of a specimen, by TMA
- -165°C to 450°C, compression, expansion & penetration modes
- Measurement of specimen weight change, by TGA with simultaneous DTA
- -25°C to 1000°C, high resolution identification of thermal events
- Determination of real and imaginary components of the complex modulus E
- withinviscoelastic materials, by DMTA
- -150°C to 600°C, multiple modes of deformation available
- Complementary temperature programmed techniques within MSG include: Reaction cell for XRD, Thermal desorption GC-MS, melt conductivity.
