ミツバ環境ソリューション List of Products and Services

At Mitsuba Environmental Solutions, we conduct "physical property investigations." We primarily perform tensile tests, bending tests, and compression tests on resin materials, as well as hardness measurements, microhardness testing, and viscoelasticity tests. For example, in Differential Scanning Calorimetry (DSC), we can evaluate the thermal properties of materials (such as endothermic and exothermic reactions due to melting and crystallization, glass transition, specific heat capacity, and thermal history) based on changes in heat flow when the temperature is varied. 【Targets】 ■ Tensile tests, bending tests, compression tests (mainly on resin materials) ■ Hardness measurements (Rockwell hardness, Vickers hardness), microhardness testing (DUH) ■ Viscoelasticity tests (DMA, rheometer) ■ Thermal properties: DSC, TGA, TMA *For more details, please refer to the related links or feel free to contact us.

At Mitsuba Environmental Solutions, we conduct "confocal microscope measurements" using a confocal microscope. The laser microscope "OPTELICS HYBRID" manufactured by Lasertec can obtain high-resolution images with a sharp focus across the entire field of view on samples with uneven surfaces. It enables non-destructive, non-contact three-dimensional shape measurement. High magnification and high-resolution observation with a 405nm laser beam allows for clear visualization of ultra-fine structures. 【Measurement Range】 ■ Width Measurement - Minimum measurement unit: 0.001μm, measurement reproducibility: 3σ < 10nm ■ Height Measurement - Scale resolution: 0.4nm, measurement reproducibility: σ < 10nm, measurement range: 7mm *For more details, please refer to the related links or feel free to contact us.

Our company conducts "X-ray Microfocus Inspection: X-ray CT Imaging." X-rays are irradiated onto the sample, which is rotated 360 degrees on the sample stage for imaging. This non-destructive method allows for the three-dimensional observation of a wide range of products, including the internal structure and defects of the sample. Due to the varying penetrability of X-rays, contrast is created based on the constituent elements (density). Elements with higher density appear bright, while those with lower density appear dark. 【Features】 - Target sample size: Diameter 150 × Height 170 mm (for vertical imaging) and up to 5 kg - X-rays are irradiated onto the sample, which is rotated 360 degrees on the sample stage for imaging - Enables three-dimensional observation of a wide range of products, including the internal structure and defects of the sample - Contrast is created based on the constituent elements (density) due to the varying penetrability of X-rays - Elements with higher density appear bright, while those with lower density appear dark *For more details, please refer to the related links or feel free to contact us.

At Mitsuba Environmental Solutions, we conduct material and defect analysis using the "Dynamic Ultra-Micro Hardness Tester." The SHIMADZU "DUH-211S" measures the relationship between the load and indentation depth at micro areas of the surface (approximately 0 to 10µm) in real-time to evaluate surface properties. In a case comparing the surface hardness of enamel coatings on copper wires, it was found that "imported products have higher surface hardness and lower elastic modulus." 【DUH-211S Specifications】 ■ Test force: 0.1 to 1961mN, minimum measurement unit 0.196μN (for tests below 1.96mN) ■ Indentation depth measurement: 0 to 10μm, minimum measurement unit 0.0001μm ■ Indenter: Triangular pyramid indenter (angle between faces 115 degrees, Berkovich type) ■ Microscope magnification: 500x (objective 50x, eyepiece 10x) ■ Types of tests: 7 types *For more details, please refer to the related links or feel free to contact us.

At Mitsuba Environmental Solutions, we conduct material and defect analysis using a "rotational rheometer." The "ARES-G2" manufactured by TA Instruments Japan Co., Ltd. can measure the thermal, mechanical, and rheological properties of polymer materials such as plastics and rubber. It employs a torsional excitation method, with measurement examples including frequency dependence, shear rate dependence, temperature dependence, and viscosity. 【ARES-G2 Specifications】 ■ Measurement temperature range: -130 to 500℃ ■ Torsional excitation method ■ Angular frequency range: 10^-7 to 628 rad/sec ■ Torque range: 0.05 μNm to 200 mNm ■ Strain range: 1 μrad to infinity ■ Geometry: Parallel plates (φ25, 50mm) *For more details, please refer to the related links or feel free to contact us.

Our company conducts dynamic mechanical analysis (DMA) of polymers. By applying a strain or stress that changes (vibrates) over time to the sample and measuring the resulting stress or strain, we assess the mechanical properties of the sample. When considered as a method of thermal analysis, it can be interpreted as a technique for measuring the mechanical properties of the sample as a function of temperature in response to vibrational loads (or strains). 【Features】 ■ Applicable to a wide range of materials by using different deformation modes ■ Capable of measuring temperature dependence and frequency dependence ■ Able to observe various relaxation phenomena, including glass transition ■ Provides information about the molecular structure and molecular motion of polymers *For more details, please refer to the related links or feel free to contact us.
