ABSTRACT:
A moisture crosslinkable flame retardant composition comprising 25-75 wt % of a vinyl trialkoxy silane copolymer having a melt index selected from the range 0.2-25, and a silane content selected from 0.5-5 wt %; 15-20 wt % polyethylene having a melt index selected from 0.1-30, and a density selected from 0.93-0.96 g/ml; 10-35 wt % decabromodiphenyl oxide; and, optionally, 5-15 wt % 1,2,3,4,7,8,9,10,13,13,14,14-dodecachloro 1,4,4a,5,6,6a,7,10,10a,11,12,12a-dodecahydro 1,4,7,10-dimethanodibenzo (a,e) cyclooctene. The crosslinkable composition provides improved dielectric breakdown strength and flame retardancy. Improved electric cables are provided.
