Element offers effective thermal conductivity and measurement services for a wide range of materials, to ensure they insulate, conduct and withstand temperature changes in Aerospace, Oil & Gas and Transportation applications.
Thermal conductivity is the material property that determines how fast or how much heat can be transferred through a material for a given temperature difference. Accurate information of a material’s thermal conductivity is crucial in heat transfer applications.
As an ISO 17025 accredited laboratory, Element can provide you with a comprehensive range of thermal conductivity testing and measurement services to help you with quantification of the thermal resistance or insulation or a coated product, and meet regulatory compliance required by governing bodies.
Thermal conductivity testing and measurement services
At Element, we can provide thermal conductivity testing and measurement of low- to medium- conductivity materials including liquids, ceramics, plastics and polymers, coatings (epoxies, resins and glues), composites and building materials.
Our thermal conductivity testing and measurement capabilities include testing to many international standards such as ASTM C518, ISO 8301 and ASTM C177. We utilize our latest state-of-art testing instrumentation to test and measure thermal conductivity and the change in thermal properties with time, temperature (up to 190 °C, down to -10 °C) and fluid absorption. Our Engaged Experts can evaluate any unique samples that you may have and create a custom testing program for your unconventional test requirements or specifications.
Thermal conductivity testing and measurements

Ceramic Thermal Barrier Coatings (TBC)
To design and predict the life of ceramic Thermal Barrier Coatings (TBCs), it is vital to understand their thermal conductivity and behavior in the presence of heat. Element uses the guarded hot plate test method to measure the temperature of ceramic TBCs samples in accordance with ASTM C177.
In addition, we can also measure thermal emissivity in TBCs, which influences heat transfer through coatings and becomes crucial as operating temperatures increase.
