Laser Thermal Conductivity (TC) testing is a sophisticated analytical method utilized to assess the thermal characteristics of materials, focusing on their heat conduction capabilities. This technique plays a pivotal role in the advancement and evaluation of eco-conscious materials engineered to reduce energy usage and promote sustainability. By offering precise insights into thermal conductivity, a critical parameter in material science governing heat transfer efficiency, this testing aids in optimizing material performance and environmental impact.
The fundamental principle behind laser thermal conductivity testing is the relationship between thermal conductivity, thermal diffusivity, and other thermophysical properties:
Thermal Conductivity = Thermal Diffusivity × Specific Heat × Density
By measuring the thermal response of a material to a controlled heat input, the thermal diffusivity can be directly determined. The specific heat and density of the sample are then used to calculate the overall thermal conductivity. This non-contact approach allows for rapid, accurate, and reliable characterization of a diverse range of environmentally-friendly materials.
Temperature Range
Samples can be tested across a broad temperature range, from cryogenic conditions to high temperatures up to 1300°C, allowing for in-depth understanding of thermal performance under diverse operating conditions.
Non-Contact Heating
The use of a laser heat source eliminates the need for direct physical contact with the sample, minimizing potential disturbances or damage to the material during testing.
Rapid and Accurate
Laser thermal conductivity analysis provides rapid, precise, and reliable data on the thermal properties of materials, enabling efficient optimization and quality control.
Small Sample Size
The technique can accommodate small sample sizes, including thin films and coatings, making it well-suited for the analysis of advanced, environmentally-friendly materials.
At CD BioSciences, we pride ourselves on offering a comprehensive Laser Thermal Conductivity Testing Service tailored to the needs of environment-friendly materials analysis.
