    摘要： A flame-retardant composition includes a crystalline propylene homopolymer or copolymer, a copolymer of ethylene with at least one alpha-olefin having from 3 to 12 carbon atoms, and optionally with a diene, the copolymer of ethylene being characterized by a composition distribution index greater than 45%, the index being defined as a weight percentage of copolymer molecules having an alpha-olefin content within 50% of an average total molar content of alpha-olefin, and natural magnesium hydroxide in amounts such as to impart flame-retardant properties. A related cable with self-extinguishing properties includes a conductor and a flame-retardant coating. The flame-retardant coating includes the flame-retardant composition. A related method for manufacturing a cable having improved mechanical properties and enhanced fire resistance includes the steps of preparing a polymer mixture with flame-retardant properties and extruding the mixture on a conductor optionally pre-coated with an insulating layer, in order to obtain a flame-retardant coating.

    摘要： Optical fibre having a glass portion and at least one coating of crosslinked polymer material surrounding the glass portion, the coating being obtained by crosslinking a mixture of at least one crosslinkable liquid composition having at least one oligomer containing at least one reactive functional group, at least one diluent monomer capable of reacting with the reactive functional group and at least one photo-initiator; at least one inorganic material with lamellar structure formed by a plurality of lamellae that have been surface-treated beforehand with a compatibilizer. The coating is formed by the crosslinked liquid composition intercalated between the lamellae of the inorganic material. Preferably, the coating is a secondary coating or, in the case of a ribbon of optical fibres, it is a common polymer coating known as a “common coating.”
