The flash technique is a well-established method for measurement of the thermal diffusivity of solids up to high temperatures. In many cases, the technique allows determination of the specific heat and therefore, a direct thermal conductivity measurement. For decades the technique was mainly used for highly conducting materials such as metals or carbon materials. Modern instruments, however, offer the capability of doing tests on low-conducting materials such as polymers or composite structures.

Presented in this webinar are measurements on polymers using NETZSCH LFA flash analyzers. The systems are equipped with high-speed Xenon flash or laser systems for generating short light pulses for heating the front side of the sample. The response signal on the back surface of the sample is measured using an InSb-IR-detector system. The systems are equipped with a furnace allowing measurements to be carried out between -125°C and 2800°C. Fast measurement times, easy sample preparation and high accuracy are only some of the advantages of this non-contact, non-destructive measurement technique.

Furthermore, the method can easily be adapted to the analysis of multi-layer samples allowing easy measurements on liquid polymers using special container systems. An overview of available container systems for liquids and powders will be given in the webinar. Furthermore, application examples on solids and liquids as well as the influence of different filling materials on thermal conductivity will be discussed.
