Dynamic viscoelasticity measurement of polyurethane rubber

We offer a variety of measurement modes, including double cantilever beam bending and three-point bending with free support!

"DMA (Dynamic Mechanical Analysis)" is an analysis method that applies periodic oscillatory loads to polymer materials and measures the resulting stress and phase difference to determine elasticity and viscosity as a function of temperature. It provides information related to molecular motion and molecular structure of polymers, such as glass transition and relaxation. 【Features】 ■ Dynamic mechanical analysis ■ Applies periodic oscillatory loads to polymer materials ■ Measures elasticity and viscosity as a function of temperature ■ Obtains information related to molecular motion and molecular structure of polymers ■ Multiple measurement modes *For more details, please refer to the PDF document or feel free to contact us.

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.

SPACECOOL Co., Ltd. is pleased to announce that it will jointly exhibit a booth with Ronsir Co., Ltd. at the "Hokkaido Energy Technology Innovation EXPO 2025," which will be held at Access Sapporo (Hokkaido) from October 8 (Wednesday) to October 9 (Thursday), 2025. Due to recent extreme heat, heat mitigation measures are also being sought in Hokkaido. At this exhibition, we will introduce heat mitigation strategies for buildings and outdoor equipment using SPACECOOL, along with actual implementation examples in Hokkaido, in collaboration with Ronsir Co., Ltd. Main Exhibition Content SPACECOOL Co., Ltd. - Explanation of SPACECOOL technology and introduction of actual implementation examples - Samples of SPACECOOL products (films, magnetic sheets, membrane materials, etc.) Ronsir Co., Ltd.: Innovation Proof RR - Actual model and implementation examples of the SPACECOOL integrated waterproof sheet "Innovation Proof RR" - Temperature sensation device for Innovation Proof RR Exhibition Overview Dates: October 8 (Wednesday) to October 9 (Thursday), 2025, 10:00 AM to 4:00 PM Venue: Hokkaido, Access Sapporo Our booth number: 405 (2 booths) *Advance registration is required for attendance (free).

The RNP-45 is a surface mount power film resistor designed to be compatible with the TO-252 package, weighing only 0.33 grams, with a thermal resistance of 3.0°C/W and a rated power of 45W. The resistive element is a pulse-resistant thick film, featuring excellent high-frequency characteristics with a reactance component of 2.7pF and 14.7nH, while also having a pulse power performance of 1kW-1µs despite its small size. The operating temperature range is from -55 °C to +175 °C. Additionally, it incorporates several design features, such as the removal of the metal flange to maximize the thermal performance of the resistor, compatibility with standard reflow SAC solder joints instead of wire bond connections, making it suitable for automatic mounting, an increased resistive element area to enhance surge performance, and the adoption of a 0.8mm substrate to strengthen bending stress.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

Hotron's vehicle detection sensors allow you to search for products that meet your needs in three categories: "Purpose of Use," "Location of Use," and "Product List." The sensors detect the passage of vehicles, alerting you with rotating lights or switching the display of parking availability. They manage vehicle presence, full parking, and exit warnings in parking lots, contributing to safe driving and smooth operational management within the parking area. They are used in various settings, from coin-operated parking to large-scale parking lots.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
