High frequency DMA testing
Mechanical testing of materials at high frequencies
Most of conventional DMA are limited to a few 10Hz and make necessary to extrapolate the data through WLF calculation to obtain high frequency properties. VHF104 is an innovative Dynamic Mechanical Analyzer that applies a direct experimental method to measure the material viscoelastic properties over a very high frequency range from 100Hz up to 10kHz.
A typical frequency sweep with VHF104 requires only a few minutes, while the test with a conventional DMA requires applying a low frequency sweep over numerous temperature stages during several hours, making necessary further WLF calculation. VHF104 allows optimizing the laboratory’s productivity by fulfilling industrial requirements for the rapid analysis of large numbers of materials formulations.
