Thermomechanical Analysis (TMA) ServiceThermomechanical Analysis (TMA) measures dimensional changes of materials as a function of temperature and load. CD BioSustainable provides TMA testing for thermal expansion coefficient, glass transition temperature, softening and melting behavior, supporting high-performance product development.
TMA applies controlled force to a sample while changing temperature, using a high-sensitivity LVDT sensor to measure dimensional changes. It detects expansion, contraction, and phase transitions, revealing viscoelastic properties, thermal stability, and mechanical behavior. Abrupt length changes indicate glass transition or melting; gradual changes reflect thermal expansion.
Coefficient of Thermal Expansion (CTE) Measurement
We offer precise measurement of the CTE for various materials, which is essential for understanding how materials expand or contract with temperature changes. This information is critical for applications where dimensional stability is required, such as in electronics and aerospace components.
Glass Transition Temperature (Tg) Determination
Our TMA service can accurately determine the Tg of polymers and other materials. This parameter is vital for understanding the material's behavior at different temperatures and is widely used in material selection and product design.
Softening and Melting Point Analysis
We provide detailed analysis of softening and melting points, which are crucial for evaluating the thermal stability and processing conditions of materials. This service is particularly valuable for the development of new polymers and thermoplastic materials.
Dimensional Stability Testing
Our TMA service assesses the dimensional stability of materials under various operating temperatures and loads. This is essential for ensuring the reliability and performance of components in real-world applications.
To ensure accurate and reliable TMA results, we work closely with our clients to carefully prepare and select the appropriate sample forms. Typical sample sizes range from 1-4 mm in thickness and up to 9.5 mm in diameter, with various geometries such as plugs, films, powders, and fibers accommodated.
Sample Preparation
Samples are carefully prepared according to the specified requirements to ensure accurate and reliable results.
Test Execution
The sample is placed in the TMA instrument, and the desired temperature program and load are applied. The dimensional changes of the sample are continuously monitored and recorded.
Data Analysis
The collected data is analyzed to determine key properties such as CTE, Tg, and softening temperature. Our team of experts provides detailed reports and interpretations of the results.
Result Reporting
Comprehensive reports are generated, highlighting the key findings and their implications for material performance and application.
