Improved flame retardant compositions suitable for insulating wire and cable products comprised of ethylene-alkoxy silane copolymer, halogenated organic compound, antimony trioxide, silane condensation catalyst and magnesium hydroxide are provided. Additionally, antioxidant(s), other mineral fillers and other conventional compounding ingredients may be included in the formulations. The compositions have good processability and are capable of being cured under ambient conditions to provide products which meet all of the specifications of SAE J-1128 for thin wall crosslinked polyolefin low tension primary cable insulation. Wire and cable products comprising a metal conductor coated with from 2 to 100 mils of the flame retardant insulation are also disclosed.
