Sumitomo Riko to Exhibit at the Automotive
Engineering Exposition 2023
- Exhibiting products in the “Sensing”, “Thermal Management” and“Hydrogen Device” fields relating to CASE –Sumitomo Riko Company Limited (Headquarters: Nakamura-ku, Nagoya-shi;
President & CEO: Kazushi Shimizu) will exhibit at a joint booth together with
Sumitomo Electric Industries, Ltd. (Chuo-ku, Osaka-shi) and Sumitomo Wiring
System, Ltd. (Yokkaichi-shi, Mie Prefecture) at the Automotive Engineering
Exposition 2023 to be held at PACIFICO Yokohama (Nishi-ku, Yokohama) from May
24 (Wed) and Aichi Sky Expo (Tokoname-shi, Aichi) from July 5 (Wed).

As the auto industry enters a period of major change, including the increase ofelectric vehicles (EV) and the acceleration of initiatives for “CASE*” to promote theadvancement of technology for self-driving cars, Sumitomo Riko is actively engaged
in the R&D of new products and materials utilizing our core competence, polymer
materials technology and comprehensive evaluation technology.
At this exhibition, we will exhibit products of the Sumitomo Riko Group with aparticular emphasis on “C: Connected”, “A: Autonomous” and “E: Electric”.

In the sensor field, we will exhibit a “Vital Sensor System”, as a product tocontribute to “Connected” and “Autonomous”.
In the thermal management field, we will show the “Film reflecting and insulating
against heat: Finesulight”, “Highly Transparent Thermal Shielding and Insulation
Film: Refleshine”, and the “Heat Insulation for Battery Cells” as products tocontribute to “Electric”.
And in the hydrogen device field, we plan to show the “Fuel Cell Gasket”.

＜Overview of exhibited products＞
C：Connected、A：Autonomous＞＞Vital Sensor System (seat-integrated type)Made into the shape of a cushion, our independently developed sensor isinstalled into the surface of the driver’s seat to detect the driver’s heart rate,breathing, body motion and other factors based on changes in pressure on theseat. The system estimates drowsiness, fatigue and other conditions from theobserved data and can connect to services such as passenger emergency response,
supervised driving support or fatigue management.

E：Electric＞＞High Performance Heat Insulation “Finesulight”
Utilizing polymer materials technology, we made ahigh-heat insulating filler (silica aerogel) containing
nanopores small enough to block the passage of air,
into a coating liquid. Then, by coating base materials
such as non-woven fabric and molded resin, this canachieve high-heat insulation properties at a level ofstill air or higher. As mobility moves toward electricvehicles (EVs), this product improves air-conditioning
in the vehicle and enables longer cruising distancethrough the suppression of electricity consumption.
>>Film reflecting and insulating against heat:
Refleshine
For building use, Refleshine blocks (thermalshielding) heat (UV) from interiors while maintaining ahigh level of transparency, and in winter, it keeps(insulation) interiors warm (far-infrared rays). Thisshielding and insulation function increases comfort andsaves energy by reducing the use of air-conditioning.
For automobile use, Refleshine ensures visibility whendriving and its insulation function controls theabsorption of heat (UV) and enhances in-vehicle
comfort.
＞＞Heat Insulation for Battery Cells
We have improved the Finesulight compound bonder
technology and developed an insulator for lithium-ion
batteries in electric vehicles (EV) which can withstandhigh temperatures of several hundred degrees Celsius.
It suppresses heat chains from developing between
adjacent cells in the case of extraordinary heat surges
and avoids major incidents which can cause fires in thevehicle. We aim to optimize this insulator by making
further adjustments to the insulation performance,
hardness and other factors in line with customer
requirements.

>> Fuel Cell Gasket (first time exhibited)Toyota Motors FCV: Supplied for the new Mirai, ourrubber seal “cell gasket” forms part of the fuel cellgasket comprised of a plate-shaped separator andpower generator and prevents hydrogen, oxygen andwater from leaking. The FC stack consists of 330 cells,
and each cell is equipped with our product.
Furthermore, the fuel cell gasket is a highly effective
seal for temperatures ranging from subzero to 100℃

FC Stackor higher. It also enables FCEVs to stay safer for longer
and generate power more efficiently.
