Thermal conductivity analysis

Introduction

Thermal conductivity is a fundamental property of materials that defines their ability to transmit heat. It is particularly important in the construction, packaging, aerospace, and automotive sectors, where the thermal performance of materials directly impacts product safety, energy efficiency, and durability.

Objective of the analysis

This analysis measures the thermal conductivity coefficient (lambda, in W/mK) of a solid material under controlled conditions. Its purpose is to:

• Characterize the thermal insulation properties
• Compare the thermal performance between several formulations
• Validate compliance with technical or normative specifications (EN, ISO, ASTM)
• Optimizing the thermal behavior of new materials

Analytical techniques used

Depending on the nature of the solid and the level of precision required, several methods are available:

• Guarded hot plate (GHP) method : for insulating materials
• Heat flow meter : for panels, films, foams
• Laser flash method (LFA) : for dense materials with high thermal performance
• Dual thermal analysis (DSC-TGA) : for complementary thermophysical characterization

Analyzed matrices

• Composite materials
• technical polymers
• Thermal insulation materials (PU, PIR, mineral wool, etc.)
• Ceramics, glass, metals
• Multi-layer packaging

Industrial applications

• Construction: Characterization of insulation materials
• Aeronautics and automotive: thermal control of structures
• Packaging: thermal barriers for sensitive products
• Electronics: Heat dissipation in devices
