Thermal Insulation Materials

Thermal insulation materials are specifically designed to reduce the heat flow by limiting heat conduction, convection and radiation. During development and quality control, the extent to which thermal insulation materials fulfill their performance expectations is continuously scrutinized. NETZSCH offers a broad range of instruments for the characterization of thermal conductivity and other properties of insulating materials.

To analyze insulations with respect to their heat transfer behavior, a heat flow meter (HFM) or guarded hot plate (GHP) is normally used. These standardized measurement methods directly yield the thermal conductivity of insulation materials or the thermal resistance of multi-layer systems.

The thermal conductivity of refractory materials is determined on large samples with hot wire systems (TCT).

Using other thermoanalytical measurement techniques, the thermal stability or composition of insulating materials can be investigated. The curing behavior of organic binders used in insulation materials can also be characterized by means of DEA (Dielectric Analysis).
