Achieving a Sustainable Society

Rare earth magnets, which are characterized by their "strong magnetic force even in small sizes," are used in the Eco-friendly cars such as electric vehicles. Silicon wafers are also an indispensable material for electric vehicles and autonomous driving. The various products of the Shin-Etsu Group support the evolution of mobility.

Shin-Etsu Group's products support Eco-friendly cars

(1) Drive motors and generators
 (Neodymium magnets)
 ・Smaller and lighter
 ・Reduced overcurrent
(2) Starters and generators
(Neodymium magnets)
(3) Power control units
 (Silicon wafers, encapsulant materials, and thermal interface materials)
 ・Smaller and lighter
 ・High sealing performance
 ・Heat-dissipating properties

The Company's neodymium magnets1 are used in drive motors and generators, which are the most important core unit of eco-friendly electric vehicles (EVs) and hybrid vehicles (HVs). The Company's silicon wafers, sealing materials, and heat dissipation materials are also used in power control units for system control.
Compared to gasoline cars, HVs can reduce carbon dioxide emissions by about 40%, while EVs can reduce emissions by 100%.* In addition, the location of the factory incorporates a carbon-neutral perspective. Our manufacturing bases for neodymium magnets are located in Fukui Prefecture of Japan and Vietnam, and at the plant in Fukui prefecture, 34% of the purchased electricity is renewable energy, and at the plant in Vietnam, 47% is renewable energy. Both of which far exceed the average ratio in Japan.
The Company is promoting the stable supply of various products used in eco-friendly cars and the development of new products, and the shipment volume of such products is increasing year by year. The Company' products are making a significant contribution to reducing CO2 emissions.

■Contributions of the Company's neodymium magnet to reducing CO2 emissions due to its use in eco-friendly car
According to the results of our calculations, the use of our neodymium magnets in eco-friendly cars reduced CO2 emissions by 280,000 tons in 2019. This will contribute to a reduction in CO2 emissions of about 3 million tons over the next 10 years.1
As a result of global carbon neutrality policies, the percentage of eco-frienfly cars has risen rapidly, and the penetration rate of EVs worldwide is expected to reach 100% by 2050.2 Demand for neodymium magnets for eco-friendly cars are expected to continue to grow. The Company will steadily respond to growing demand.
