The SEKISUI CHEMICAL Group provides materials that contribute to improving the reliability of ADAS devices, especially the bonding, heat dissipation, and molding technologies we have developed over time.
Challenge
With the evolution of ADAS (Advanced Driver-Assistance Systems), vehicles are being equipped with more and more electronic parts that work to achieve driver safety and comfort, and with this, a range of new issues are cropping up.
For example, we need methods to combat heat in order to prevent safety or performance drops due to the heat generated as electronic parts become more advanced and smaller, and to prevent operation errors due to interference from electromagnetic noise. So, there are increasing needs for heat dissipation and electromagnetic shielding in the materials that make up devices. In particular, there is a strong demand that the performance, safety, and reliability of sensors parts such as radars and cameras that detect what is going on inside and outside the vehicle, and the ECU (Electronic Control Unit) that processes and judges information, be upgraded. In addition, the increase in weight with these added parts means that even as vehicle electrification advances, there are impacts on range, so combining these parts with lightness is a key element.
Solution
The SEKISUI CHEMICAL Group provides materials that contribute to improving the reliability of ADAS devices, especially the bonding, heat dissipation, and molding technologies we have developed over time. Our lineup includes greases and sheet-type heat dissipation products that allow cooling for hot parts such as CPUs and GPUs, and housings for millimeter wave radar or in-vehicle cameras, allowing us to offer materials that combine flexibility, insulation, and are siloxane-free. In addition, for thin noise-absorbing materials that use our sputtering technology and injection-molded products that balance heat dissipation with electromagnetic shielding, we have the technologies to lighten materials or parts by replacing the conventional metal or rubber parts. Also, we shall contribute to improving the reliability of ADAS devices through sealing functions using bonding technology and gap control for PCBs (Printed Circuit Board) that are getting thinner through functional microparticles technology.

The SEKISUI CHEMICAL Group provides materials that contribute to improving the safety and performance of batteries, especially the bonding, heat dissipation, and molding technologies we have developed over time.
Challenge
Managing battery temperatures is considered important in order to maintain performance stability, safety, and battery life for EVs (electric vehicles).
For example, in low temperatures, the internal resistance of battery cells increases, affecting performance and lifespan, and this may prevent proper charging. In high temperatures, there are effects on output density, causing drops in acceleration performance and thermal runaway, which can damage the battery and cause fires. In addition, to improve the range of EVs, LiB are becoming increasingly higher in capacity, so both lightness and safety need to be balanced. Moreover, there are also the background issues of global warming and the energy problem, so the needs for environmentally-friendly materials for making automobile parts is growing more and more.
Solution
The SEKISUI CHEMICAL Group provides materials that contribute to improving the safety and performance of batteries, especially the bonding, heat dissipation, and molding technologies we have developed over time. For example, in our heat dissipation products, which are well regarded for their reliability when used in EV batteries in Europe, we have a lineup of grease and sheet-type products, and can provide materials that offer flexibility, adhesiveness, low volatility, low density, and so on. In addition, we have technologies that contribute to the safety of battery packs such as shock-absorbing materials that combine low flammability with superior thermal insulation and heat retention properties, fire protection materials that prevent fires from spreading by expanding to create a thermal barrier when a fire breaks out, and thermoplastic resin sheets (currently under development) that combine inflammability, fire retardation, and thermal insulation. In addition, we are working on the development of environmentally-friendly products that use plant-based or recycled raw materials, contributing to the reduction of CO2 emissions.

The SEKISUI CHEMICAL Group provides materials that contribute to improving the design and comfort of upcoming vehicles, especially the bonding, heat dissipation, and molding technologies we have developed over time.
Challenge
As automated driving evolves, cars are changing from methods of transport to “mobile living rooms.”
At the same time, a lot of systems need to be installed to achieve automated driving, such as ADAS (Advanced Driver-Assistance Systems) and HMI (Human-Machine Interface). These need to immediately present information to the driver during an emergency, and encourage both safe and smooth operations. For that reason, designs that seamlessly blend HMI and conventional interior décor are required in order to balance both safety and the comfort of your living room. In addition, with the reduction of CO2 emissions as a way to counter global warming being a global issue, the shift to EVs (electric vehicles) is moving rapidly. Even as we pursue lightness to increase range, there is an increasing need for materials that can create a sense of high class and comfort through senses other than sight, such as touch.
Solution
The SEKISUI CHEMICAL Group provides materials that contribute to improving the design and comfort of upcoming vehicles, especially the bonding, heat dissipation, and molding technologies we have developed over time.
For example, interlayer films for laminated glass do not stop at just preventing glass from shattering, their core conventional function, but now allow a range of colored designs to be applied. "In addition, combinations of different solutions such as sound deadening or thermal insulation, or wedge-shaped interlayer films for head-up displays (HUD) contribute to the comfort and safe of vehicle interiors. Capacitive touch sensors can respond to a variety of input methods, and allow both designs to be applied and 3D-forming. We are developing a foam that can give a pleasant feel without ruining light displays which will improve the added value of conventional interior cushioning materials, and through combinations of these technologies, we can offer new display designs. In addition, we are moving ahead with proposals to improve the comfort of vehicle interiors and improve the reliability of next-generation HMI devices through increasing the functionality of bonded materials by adding low-odor, low-VOC and high heat resistance as well as increased lightness and improved design by drawing on sputtering technology and injection molding technology.
