Thermal conductivity is a measure of a material’s ability to transfer heat and thermal diffusivity measures the rate of heat transfer. Together with specific heat capacity, these thermophysical property measurements offer comprehensive informationon a material’s ability to store and transfer heat. The precise and accurate measurement of heat transfer properties is critical for materials that are required to insulate, conduct, or simply withstand temperature changes.
The thermophysical properties of thermal conductivity, diffusivity, and specific heat capacity can be determined with heat flow meters and laser flash (or light flash) analyzers. Thermal conductivity of insulation and construction materials that include polymers, composites, ceramics and refractories are typically measured on a heat flow meter. . Laser and Light flash analyzers can be used to determine all three properties of a diverse array of materials over a wide range of test conditions with unparalleled accuracy. The measurement of heat energy storage and transfer empower all stages of material selection and product design with comprehensive heat transfer modeling and critical information about material composition, purity, structure, and performance characteristics.
