DMA (Dynamic Mechanical Analysis)

We would like to introduce our "Chemical Analysis - Trust Us Service." When conducting component analysis of foreign substances or stains on products, it can be challenging to determine whether organic analysis or inorganic analysis is more suitable, and which specific analysis within organic or inorganic is the most appropriate. We provide a comprehensive service for customers who are struggling with the selection of analysis methods. Since each analysis device can measure different targets, it is necessary to choose a method that fits the purpose based on the information available.

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)
