Control of Humidity and Underwater Environment
Viscoelasticity Measurement



The physical properties of moisture-absorbent materials vary significantly with the water absorption rate.
Hence, the physical properties in an actual use environment are evaluated by making dynamic viscoelasticity measurement with humidity and underwater environment under control.
