Hydrogen Tank Liner
In most Fuel Cell Electric Vehicles (FCEVs), the H2 fuel is stored in a high-pressure tank made from a plastic liner encased in a composite wrap. The key role of the plastic liner is to keep the hydrogen from permeating out of the tank, even at very high pressures. Additionally, it is critical to the safety of the FCEV that this liner is also very durable, especially at cold temperatures.
Rilsan® PA11 provides a great combination of permeation resistance and cold temperature durability for H2 tank liners. It also has excellent resistance to tank blistering and crack propagation. Rilsan® PA11 is very easily processed and can be used to make hydrogen tank liners via rotomolding, extrusion blow molding, injection molding, and extrusion.
