Latest Trends in the Automotive Market
  • Today, the automotive industry is undergoing a “once-in-a-century revolutionary change.” These changes are often referred by the acronym CASE, standing for Connected, Autonomous, Shared & Services and Electric. While trends on these four fronts promise improved user convenience, they are expected to pose major challenges to the industry, prompting automotive and related businesses to undertake thoroughgoing restructuring. In other words, right now industry conditions are conducive to the creation of new businesses that may eventually achieve significant growth.
    Under the Denka Value-Up management plan, we are placing strong focus on automotive-related operations as part of the environment and energy, which we have positioned as a priority field. We will provide essential materials and solutions supporting the aforementioned trends, thereby expanding these operations.

Social Issues

Among the issues confronting the automotive industry, the reduction of its environmental footprint and the prevention of traffic accidents are paramount. In the face of growing public concerns about the environment, regulatory standards enforced by EU members and other major countries to limit CO2 emissions from vehicles are becoming ever more stringent due to the looming threats of air pollution, global warming and other detrimental phenomena affecting countries worldwide. If automakers are to be able to meet these standards, it is essential that the use of electric vehicles (EVs) gains popularity and vehicle weights are reduced.
In Japan, the growing number of car accidents involving elderly drivers is a public concern. On a global basis, approximately 1.3 million people die in car accidents every year. Against this backdrop, automakers are called upon to realize a safe, reliable and fully autonomous driving system so that one day the occurrence of such accidents can be reduced to zero. This technology is also expected to help resolve such issues as how to improve mobility for people with disabilities and how to compensate for the shortage in human drivers.

Denka’s Strengths in the Automotive Field
High-heat conductive ceramic substrates
Popularization of EVs (the environment)

Denka’s ceramics-based electronic circuit substrates are made using nitride ceramic powder manufactured in a high-temperature environment at 2,000ºC and boast such features as high-heat conductivity, electric insulation, smaller thermal expansion and superior toughness. These substrates are used in automobile, railcar and industrial instrument power modules that are increasingly expected to achieve higher output and to be compact in size.

High-heat conductive ceramic substrates

Acetylene black
Popularization of EVs (the environment)

Carbon black is one of our specialty products. It is manufactured by decomposing acetylene via high-temperature combustion and is known for ultra-high purity. Thanks to its unique, chain-like structure consisting of a string of colloidal micro particles of carbon, this product boasts electro and thermal conductivity as well as liquid absorbency, among other features. Since the 1942 launch of its production, Denka has supplied acetylene black for use as a conductive aid for batteries, a material for the semiconductor layers of ultrahigh-voltage cables and other applications requiring high reliability.

Spherical alumina filler
Popularization of EVs (the environment)

This product is used as an additive that gives resins and elastomers superior heat conductivity. The application of Denka’s unique high-temperature fusing technologies gives the filler superior purity, liquidity and sphericity and it is used as a key thermal solution material capable of supporting the creation of miniaturized electronic devices with greater capacity.
