Orientation effects, stretch conditions and shrinkage are measured under load for films. In this example, the expansion and contraction behavior of a 40-μm thick polycarbonate film was tested under tensile load. The results varied considerably depending on the load. Under low amounts of force (5 mN), the film contracted at higher temperatures; however, it expanded if greater force (50 mN) was applied. (measurement with TMA 402 F1/F3 Hyperion®)
TMA 402 F1/F3 Hyperion® - Thermomechanical Analyzer
What sets the TMA 402 F1/F3 Hyperion® apart is the modular concept of interchangeable furnaces covering the temperature range from -150°C to 1550°C, which are also compatible with other NETZSCH instruments. A large number of sample holder types and adjustment possibilities are available. The TMA 402 F1/F3 Hyperion® can be operated with a broad range of force, without added weight, digitally programmable from -3 N to 3 N.
