Analysis of thermal expansion of solids

Thermal expansion analysis of solids measures the increase in length, surface area, or volume of a material as a function of temperature. It is essential for evaluating the behavior of materials subjected to thermal variations, preventing mechanical stress, or ensuring compatibility between components in assemblies. This analysis is particularly useful in the fields of polymers, composites, construction materials, packaging, and coatings.

Performed using a dilatometer, this method provides the coefficient of linear thermal expansion (CTE), expressed in µm/m·°C, over a defined temperature range. It makes it possible to anticipate deformation, cracking or decoupling phenomena in environments subject to thermal cycles.

Typical matrices include: plastics, composite materials, elastomers, metals, ceramics, wood, technical papers, etc.

At YesWeLab , we collaborate with a rigorously selected network of laboratories, most of which are certified and/or accredited (ISO 17025, COFRAC, etc.). These laboratories are chosen based on your specific needs, the matrices to be analyzed, and the analytical techniques or methods required.
