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.
作为ISO 17025认可的实验室,元件可以为您提供全面的导热性测试和测量服务,以帮助您定量热阻或绝缘或涂层产品,并满足控制机构所需的调节顺应性。
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.
我们的导热性测试和测量能力包括测试许多国际标准,如ASTM C518,ISO 8301和ASTM C177。我们利用我们最新的最先进的测试仪器来测试和测量热导电性和热性能变化随时间,温度(高达190°C,低至-10°C)和流体吸收。我们的订阅专家可以评估您可能拥有的任何独特样本,并为您的非传统测试要求或规格创建自定义测试程序。

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.
