Thermal Expansion Coefficient by TMA
This test measures thermal expansion coeffient using a thermomechanical analyzer fitted with quartz expansion fixture. The normal temperature range is 0°C to 60°C. Data are taken in the flow (0 degree orientation) direction.
Other test orientations can be specified. Other temperature ranges can be used, up to the melt temperature of the material. This test can be adapted for soft materials and films. Please contact us with details; additional costs may apply.

Data is used for design purposes and to determine if failure by thermal stress may occur when a part composed of two different materials is subjected to a change in temperature. This test is useful to determine thermal expansion of materials in which anisotropy is not suspected.
