  • METHOD FOR MANUFACTURING A SEALING BLADDER MADE OF THERMOSETTING POLYMER FOR A TANK CONTAINING A PRESSURIZED FLUID, SUCH AS A COMPOSITE TANK, AND A TANK
    Publication number: 20160023381
    Abstract: A method for manufacturing a polymer bladder assuring the internal sealing of a tank vis-à-vis a pressurized fluid which is contained therein, wherein said polymer is a thermosetting polymer, and said method comprises at least one step of polymerizing at least two precursor compounds of said thermosetting polymer carried out in a mould in rotation. A tank for storing a pressurized fluid for example a type IV tank comprising said polymer bladder.

  • Method for making a part with clearance volume by rotational moulding and resulting part
    Patent number: 7247268
    Abstract: A cylindrical element is manufactured by a process which includes depositing successive layers of thermoplastic materials in a cycle by rotation moulding, or by a technique enabling a deposit of successive layers, the cycle including at least one deposit by rotation moulding or by a technique enabling deposit of successive layers at a temperature from 170 to 240° C. The cylindrical element contains at least one layer containing an ethylene-vinyl alcohol copolymer with a density at the above temperature of between 0.94 and 1.4, and a melt flow index of between 1.3 and 4.2 g/10 minutes.
