Abstract

''CABO, E, COMPOSIçãO RETARDADORA DE CHAMA'' Cabos, em particular cabos elétricos para a transmissão de energia de baixa voltagem ou para telecomunicações, ou, alternativamente, para a transmissão de dados, ou cabos mistos para energia/telecomunicações, que apresentam propriedades de auto-extinção e que produzem um baixo nível de fumaça, em que está presente uma camada de revestimento à base de um material de polímero e uma carga inorgânica retardadora de chama. O material de polímero compreende um copolímero de heterofase com uma fase elastomérica à base de etileno copolimerizado com uma <244>-olefina e uma fase termoplástica à base de propileno. A fase elastomérica consiste em pelo menos 45% em peso relativamente ao peso total do copolímero de heterofase e o copolímero de heterofase é substancialmente isento de cristalinidade derivada de sequências de polietileno.'' CABLE, E, FLAME RETARDANT COMPOSITION '' Cables, in particular electrical cables for the transmission of low voltage energy or for telecommunications, or, alternatively, for data transmission, or mixed cables for energy / telecommunications, which present self-extinguishing properties that produce a low level of smoke, in which a coating layer based on a polymer material and an inorganic flame retardant charge is present. The polymer material comprises a heterophase copolymer with an elastomeric phase based on ethylene copolymerized with an β-olefin and a thermoplastic phase based on propylene. The elastomeric phase consists of at least 45% by weight relative to the total weight of the heterophase copolymer and the heterophase copolymer is substantially free of crystallinity derived from polyethylene sequences.
