Thermal Analysis

Thermal Conductivity

Properties Measured

A material’s Thermal Conductivity is its ability to transfer heat. Exact measurements of TC are essential for understanding and optimizing energy efficiency and predicting thermal performance of materials in a wide range of industries including energy, construction, electronics, aerospace, and automotive. This property can be significantly affected by absorption of fluids from an operating environment, such as in the case of subsea thermal insulation materials.
