Evaluation of thermal degradation rubber by DMA

Dynamic mechanical analysis (DMA) allows for the evaluation of states from low to high temperatures.

This introduces the evaluation of thermally degraded rubber using dynamic viscoelastic measurements. A constant temperature bath capable of circulating air within the chamber was used as a suitable device for thermal degradation testing, heating NBR rubber and EPDM rubber at 100°C for a specified duration. The changes in viscoelastic behavior due to heating time were investigated. For both types of rubber, as the heating time increased, the tanδ (= E"/E') peak shifted towards the high-temperature side, and a decrease in peak value was observed. It is believed that the loss of rubber elasticity and the decrease in elastic modulus resulted in the Tg shifting towards the high-temperature side. By measuring dynamic viscoelasticity, it becomes possible to confirm the changes in physical properties associated with material degradation and to gain insights into structural changes. Additionally, conducting other chemical analyses can clarify more specific changes in chemical structure. 【Test Overview】 ■ A constant temperature bath capable of circulating air within the chamber was used ■ NBR rubber and EPDM rubber were heated at 100°C for a specified duration ■ Changes in viscoelastic behavior due to heating time were investigated *For more details, please download the PDF or feel free to contact us.

The seismic sensor device "HK-2" detects strong tremors equivalent to a seismic intensity of 5 or higher, transmits a signal to the control room, and emergency stops the facility equipment. 【Installation Location】 Automotive parts factory 【Challenges】 Due to the maintenance and replacement of the factory equipment control devices, we considered updating the existing seismic sensors as well, but since production had already ended, we were looking for alternatives. 【Effects After Installation】 The HK-2 has the function to emergency stop equipment during an earthquake, and since its functionality is the same as the existing device, it was introduced as a replacement. Its compact size also allowed it to fit within the existing control panel being used. ★See more examples of the seismic sensor device "HK-2" https://www.hotron.co.jp/recommend/HK-2_lp.html#anchor_a04 ◎For more details, please download the materials or contact us.

[To the owners of parking lots and parking lot construction companies] "I am worried about the possibility of colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as pedestrian collisions and vehicle-to-vehicle accidents. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures at various sites and alerts the surrounding area with LED lights and buzzers. The system consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *When using the exit warning system, we kindly ask that you arrange for the switching power supply (24V), LED rotating light, control panel, circuit breaker, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. [Contents Included] ○ Exit Warning System Configuration ○ Comparison Table of Exit Warning Sensors ○ Four Modes ○ Wide Range of Applications ○ Customer Feedback ○ Appearance Diagram / Specifications ◎ For more details, please contact us or download the catalog.

In facilities operating nurse call systems, we have made bed exit sensors wireless, allowing them to notify in conjunction with the nurse call system. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. This helps prevent accidents caused by falls, slips, or wandering, contributing to the efficiency of medical operations. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ Bed exit sensors notify wirelessly in conjunction with the nurse call system. ○ Up to 5 transmitters can be registered with one receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.

We have renewed our brochure regarding "Soil Contamination Investigation and Measures." Soil contamination investigation and measures require complex and specialized knowledge, including legal regulations, investigation obligations, and countermeasure methods. In this brochure, we have systematically organized the overview of legal regulations and various countermeasures to make it easier for those unfamiliar with the Soil Contamination Countermeasures Act and the Water Pollution Prevention Act to understand. Additionally, we have included a flowchart indicating "when soil investigation is necessary," allowing businesses to grasp the relevant situations for themselves. By clarifying "what needs to be done now," we support decision-making for companies engaged in environmental risk management. The structure is designed to be easy to understand even for those encountering the Soil Contamination Countermeasures Act for the first time, so please take a look. For more details, please refer to the news page on our company website linked in the related links section. 【Contact Information】 Mitsubishi Material Tech Corporation, Sales Planning Department (Weekdays 9 AM - 5 PM) 03-6628-6905 or contact form

"This company has a nice atmosphere..." The reason might be the "scent" of the space. Why scent in the office now? Just by introducing scent, the quality of the office dramatically improves. 1. Visitor Reception: Enhancing the Quality of Hospitality Just having a pleasant scent wafting through the entrance and reception room gives visitors a positive first impression of a company that pays attention to detail. 2. Increased Concentration: Towards a More Productive Workplace Scent directly brings relaxation and refreshment effects to the brain. It supports mood changes during work breaks and helps maintain concentration during long hours of desk work, leading to improved employee performance. 3. Enhanced Corporate Image (Branding) The memory of "that office always has a nice scent" quietly and surely enhances the company's brand image. It becomes a powerful tool for differentiating from other companies. Start with a "Free Trial Installation" If you want to improve the atmosphere of your office and create a more comfortable working environment for your employees, why not try the power of scent?
