COMPOSITE MATERIAL COMPOSITION FOR NEUTRALIZING ACIDIC COMPOUNDS AND CONDUCT COMPRISING A SHEATH COMPRISING SUCH A COMPOSITION

摘要

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