Dynamic viscoelastic measurement of polyurethane rubber.
It is also possible to create master curves in tensile, shear, and bending modes other than compression mode!
We would like to introduce the quality technology of AITES Co., Ltd., specifically regarding the dynamic viscoelasticity measurement of polyurethane rubber. DMA is an analysis that applies periodic vibrational 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 indicate that the glass transition temperature is -15.7°C, as shown by 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 ■ Free-supported three-point bending ■ Shear (sliding) *For more details, please refer to the PDF document or feel free to contact us.

Evaluation of tensile properties using a stretch gauge for high-stretch flexible materials.
We would like to introduce the "Tensile Property Evaluation using Extensometers for High-Elasticity Flexible Materials" that we offer. Tensile tests of NR rubber will be conducted using contact-type (suitable for high-elasticity and soft materials) and non-contact type (video) extensometers, and the results will be compared. To accurately determine strain in tensile tests, it is necessary to select the appropriate extensometer and testing conditions based on the target material and measurement objectives. We will provide suggestions tailored to your consultation needs.

Dynamic viscoelasticity measurement of polyurethane rubber
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)
