The No. 1 thermo-analytical method for polymers is DSC (Differential Scanning Calorimetry), with which thermal effects and derived parameters for such effects as melting, crystallization, crosslinking, glass transition, specific heat capacity, and oxidation can be investigated.

TGA (Thermogravimetry) provides information about the composition and thermostability of polymers, polymer mixtures and blends. In addition, gas analyses can be performed via coupling with QMS (Quadrupole Mass Spectrometry) or FT-IR (Fourier Transform Infrared Spectroscopy).

Dilatometry and TMA (Thermomechanical Analysis) yield information on expansion or shrinkage behavior as well as on the coefficient of thermal expansion. DMA (Dynamic Mechanical Analysis) also provides values for the coefficient of elasticity and information regarding visco-elastic behavior, aging, creep and relaxation.

With DEA (Dielectric Analysis), the curing behavior of reactive resin systems can be measured, even during processing.

LFA (Laser/Light Flash Analysis) measures the thermal diffusivity (even for thermoplastic melts); using that information, the thermal conductivity can then be calculated. A tried and tested method for determining the thermal conductivity of polymer isolation foams is the measurement of heat flow by means of HFM.
