PROCESS FOR PRODUCING SELF-EXTINGUISHING CABLES WITH LOW-LEVEL PRODUCTION OF FUMES, AND FLAME-RETARDANT COMPOSITIONS USED THEREIN

摘要

Process for producing cables, in particular electrical cables for low-voltag e power transmission or for telecommunications, which have self-extinguishing properties and produce a low level of fumes, in which the flame-retardant coating layer is obtained by extruding a flame-retardant composition comprising a polymer base, an inorganic flame-retardant filler and a dehydrating agent. The presence of the dehydrating agent makes it possible t o obtain a smooth and uniform flame-retardant layer which is virtually free of pores.
