UBE Corporation announced that it is supplying polyamide (nylon) 6 resin for the new Crown FCEV recently released by Toyota Motor Corporation.

Sold commercially as UBE NYLON 1218IU, the nylon 6 resin was co-developed by Toyota Motor and UBE for use as a plastic liner material in the high-pressure hydrogen tank for fuel cell vehicles (FCVs). This marks the second Toyota Motor fuel cell passenger vehicle model, following the MIRAI, to use UBE’s nylon 6 resin.

UBE NYLON 1218IU satisfies the stringent standards to be approved as a plastic liner material for the high-pressure hydrogen tank in the Crown FCEV. As the innermost component (inner liner) of the tank, the plastic liner prevents hydrogen from leaking out of the tank.

The nylon 6 resin delivers superior performance for hydrogen permeation prevention and excellent mechanical performance, in terms of durability to withstand sudden changes in tank temperature from filling and discharging hydrogen, and impact resistance in low-temperature environments.
