Dynamic viscoelasticity measurement of polyurethane rubber

アイテス

We would like to introduce the dynamic viscoelasticity measurement of polyurethane rubber conducted by Aites Co., Ltd. DMA is an analysis that applies periodic oscillating loads to polymer materials and measures elasticity and viscosity as a function of temperature from the resulting stress and phase difference. In this instance, we conducted measurements using cylindrical rubber samples in compression mode. The measurement results indicated a glass transition temperature of -15.7°C from the temperature dispersion curve of Tan δ, and we created a master curve based on the time-temperature superposition principle. Please feel free to consult us when needed. 【Methods of Applying Load】 ■ Tension ■ Compression ■ Bending with both ends supported ■ Three-point bending with free support ■ Shear (sliding)
