Thermal Expansion Coefficient by TMA (Anisotropic)
This test measures thermal expansion coefficient using a thermomechanical analyzer fitted with quartz thermal expansion fixture. The normal temperature range is 0°C to 60°C. Data are taken in flow and x-flow directions to determine anisotropy.
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.

1 - plaques (4 x 12in)
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 used to determine the thermal expansion of anisotropic materials.
