thermo-mechanical analysis
Precise determination of the dimensional change (thermal expansion coefficient)
| investigation method | thermo-mechanical analysis |
| Device type and equipment | TMA Q400 with MCA cooler (TA Instruments) |
| functional principle | Determination of dimensional changes of solids, liquids or pasty materials as a function of temperature and/or time under defined static mechanical load. |
| Typical applications | Plastics and elastomers, paints and varnishes, composites, adhesives, films and fibers, ceramics, glasses, metals or composites |
| measurement technology | Expansion, penetration, three-point bending, compression, tension measurement modes: shear stress/deformation, creep and shear stress relaxation, thermal expansion, softening point determination, resistance temperature |
| Norms and standards | DIN 51 005, ASTM D 3386, ASTM E 831, ASTM D 696, ISO 11359 – Teil 1 bis 3 |
| Requirements for sample | max. 26 mm (L) and 10 mm (D) for solid samples max. 25 mm (L), 0.35-1.00 mm (H) and 4.7 mm (W) for films and fibers |
