BSEF Japan meets with Nissan Motor Corporation

BSEF Japan has reinforced its relations with Nissan Motor Corporation, a Japanese multinational automobile manufacturer headquartered in Yokohama, Japan.

During a recent meeting of the Society of Flame Retardant Materials in Japan, Kazuya Okazaki o fNissan’s Materials and Technology Division, gave a presentation on “flame retardant materials in automobiles”.

The key message from the presentation was that while automotive manufacturers are using resins in EV battery cases to lower the weight of EVs, there are concerns over the battery cases’ flame retardancy.  Flame retardant material is needed to improve the flame retardancy performance of resin-based battery cases, but as regulation in this area gets stricter, they find their options for flame retardant materials decreasing.

Kazuya Okazaki told the audience how all new Nissan vehicles introduced in major markets will be electric vehicle (EVs) by early 2030.  According to the presentation, EVs are 200-400kg heavier than comparable conventional engine-powered cars, making it necessary to use new innovative and lighter plastic materials, materials that often need to be protected by flame retardants.

Nissan and other automotive manufacturers are using new resins in EV battery cases to decrease the overall weight of EVs.  One of Nissan’s concerns is the fire resistance of the resins and therefore the safety of the driver and passenger.  Since EVs’ large batteries easily generate heat, Nissan needs to respond to the new fire-retardant regulations that are being implemented “as a trend towards increasing regulations for the heat resistance and flame retardancy of both the interior and exterior (of automobiles)”.

BSEF Japan continues to keep in close contact with Nissan, and other automotive manufacturers in Japan, to monitor relevant developments in the sector.
