Abstract: The present invention relates to a fire resistant material comprising a matrix of thermosetting elastomeric resin of the silicone resin type wherein endothermic fillers are incorporated as well as to a high pressure storage tank coated with said material, processes for the preparation thereof and uses thereof.

Abstract: The present invention relates to a method for manufacturing an internal shell of a composite type IV reservoir delimiting an internal cavity intended to accommodate a pressurized fluid and comprising at least one metal baseplate allowing connection between said internal cavity and the outside of the internal shell, said baseplate or baseplates being secured to the internal shell, said method comprising the following steps: a) a step of applying at least one adhesive layer of a first polymer to the part or parts of the metal baseplate or baseplates intended to be in direct contact with the material of which the internal shell is made; b) a step of incorporating said baseplate or baseplates thus coated into a mould the internal cavity of which is of a shape that corresponds to the shape of the internal shell that is to be obtained; c) a step of forming, on the internal wall of the mould and on the part or parts of the baseplate or baseplates intended to be in contact with the material of which the internal s

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.

Abstract: Poisoned modified polymer of poly(ethynylene phenylene ethynylene silylene) type that may be obtained by selective addition of a compound containing only one reactive function to the acetylenic bonds of a poly(ethynylene phenylene ethynylene silylene) polymer. Compositions containing these modified polymers. Process for preparing these modified polymers. Novel self-poisoned polymers of poly(ethynylene phenylene ethynylene silylene) type. Cured products that may be obtained by heat treatment of the said modified or self-poisoned polymers. The polymers and cured products have improved mechanical properties while maintaining excellent thermal properties.

Abstract: Composition comprising a blend of at least one poly(ethynylene phenylene ethynylene silylene) polymer and of at least one compound capable of exerting a plasticizing effect in the blend, once this blend has been cured.
