PIPE COMPRISING A SHEATH MADE FROM A COMPOSITE MATERIAL COMPOSITION FOR NEUTRALIZING ACID COMPOUNDS

The invention relates, on the one hand, to a composite material composition capable of neutralizing acid compounds and of being used under high temperature conditions, said composition being a mixture of a polymer material with a predetermined amount of reactive fillers, the mass fraction of the che...

More Information
Summary:The invention relates, on the one hand, to a composite material composition capable of neutralizing acid compounds and of being used under high temperature conditions, said composition being a mixture of a polymer material with a predetermined amount of reactive fillers, the mass fraction of the chemically active products ranges between 4 and 40% and the polymer material is selected from the vinylidene fluoride copolymers family, comprising a vinylidene fluoride monomer, and at least one monomer being selected from among the following monomers: hexafluoropropylene, perfluoro(methylvinyl)ether, perfluoro(ethylvinyl)ether, perfluoro (propylvinyl)ether, tetrafluoroethylene, perfluorobutylethylene, fluoropropylene, chlorotrifluoroethylene, chlorodifluoroethylene, chlorofluoroethylene, trifluoroethylene, and the monomer with the following formulation: CH2 CH-CF2-(CF2)4-CF3 and, on the other hand, to a pipe comprising at least one sheath made from the composite material composition.
