Beschreibung
Zusammenfassung:A flame-retardant cable (10;20) having a transmissive core and an outermost layer (13a;14) made from a flame-retardant polymer composition comprising:a) 100 phr of polyvinylchloride (PVC) as base polymer;b) 65-90 phr of a metal hydroxide;c) 2-9 phr of antimony trioxide;d) 1-3 phr of an optionally surface-modified sepiolite, ande) 3-10 phr of a Ca/Zn stabilizer.Such a cable has improved reaction to fire performances, in particular a reduced or null dripping under fire.
