Abstract

"PROCESSO PARA PRODUZIR CABOS AUTO-EXTINTORES COM PRODUçãO DE BAIXO NìVEL DE FUMOS, E, COMPOSIçãO RETARDANTE DE CHAMAS" Processo para produzir cabos, em particular cabos elétricos para transmissão de energia de baixa voltagem ou para telecomunicações, que têm propriedades auto-extintoras e produzem um baixo nível de fumos, em que a camada de revestimento retardante de chama é obtida extrusando-se uma composição retardante de chama compreendendo uma base polimérica, uma carga retardante de chama inorgânica e um agente desidratante. A presença do agente desidratante torna possível obter-se uma lisa e uniforme camada retardante de chamas, que é virtualmente livre de poros."PROCESS TO PRODUCE SELF-EXTINGUISHING CABLES WITH LOW SMOKE PRODUCTION, AND, FLAME RETARDANT COMPOSITION" Process to produce cables, in particular electrical cables for transmission of low voltage energy or for telecommunications, which have self-extinguishing properties and they produce a low smoke level, in which the flame retardant coating layer is obtained by extruding a flame retardant composition comprising a polymeric base, an inorganic flame retardant filler and a dehydrating agent. The presence of the dehydrating agent makes it possible to obtain a smooth and uniform flame retardant layer, which is virtually free of pores.
