Coefficient of Linear Thermal Expansion Textile Testing
Applus+ Reliable Analysis performs precise coefficient of linear thermal expansion (CTE) testing by thermomechanical analysis (TMA) that helps textile and medical device manufacturers measure how materials expand or contract with temperature changes. Additionally, our testing helps manufacturers verify dimensional stability and predict material performance across changing environments. We build these capabilities on our established thermal analysis and dimensional stability expertise.
Our ISO/IEC 17025-accredited laboratory uses proven TMA systems and environmental chambers to deliver accurate and repeatable results. As a result, you receive dependable CTE data for coated medical textiles, synthetic leather, barrier films, laminates, and technical components that require dimensional stability during sterilization, storage, and temperature fluctuations.
Coefficient of linear thermal expansion testing uses thermomechanical analysis to measure changes in material length as temperature increases or decreases. Next, we calculate the CTE value in µm/m·°C across the required temperature range. This testing helps manufacturers qualify medical seating materials, exam table covers, synthetic leather, coated barrier fabrics, and medical device components. These products must maintain precise dimensions during autoclave cycles, cold storage, and everyday temperature changes.
Additionally, our laboratory performs every evaluation with advanced TMA systems, thermal chambers, and supporting mechanical equipment. Our experienced team prepares each specimen carefully, conducts controlled heating and cooling ramps, and records detailed expansion curves with calculated CTE values. Consequently, you receive accurate, consistent, and traceable results.
