    Desman Display Polyamide Composite Gas Storage Tank

    Business Association, Nov. 07
    Recently, at the Fakuma exhibition in Germany, Desman exhibited a gas tank equipped with blow moulded inner liner using Akulon fuel oil barrier, a polyamide-based engineering plastics with very high hydrocarbon barrier. The tank can be coated with composite fibers based on thermosetting or thermoplastic resin, such as tape made of Eco PaXX polyamide 410, which is suitable for blow moulding of the inner liner of large pressure vessels for heavy vehicles such as buses and trucks.
    It is reported that the traditional 40L steel tank weighs about 60 kg, while the Akulon fuel barrier IV tank weighs only 20 kg. Carbon dioxide can be reduced by about 1 g/km for every 10 kg reduction in vehicle mass.
    In addition, Desman developed composite fibers for vessel cladding using thermoplastic materials such as Eco PaXX polyamide 410 or another grade of Akulon, thus successfully realizing the joint development of the next generation V-type pressure vessels. The mass of V-type pressure vessel is about 70% less than that of steel tank and lighter than that of IV-type pressure vessel. This kind of material is more durable than steel, has better chemical resistance and can be completely recycled. Another advantage of Eco PaXX is that its polymers are made entirely from renewable resources, so the total carbon emissions are zero throughout the life cycle.
