ABSTRACT:
Improved flame retardant moisture curable insulation compositions are comprised of an ethylene-alkoxysilane copolymer, a halogenated anhydride and antimony trioxide provided. The compositions have good processability and can be moisture cured to provide products which meet all of the requirements for SAE J-1128 low tension primary cable. The halogenated anhydride imparts flame retardancy to the compositions and also promotes cure by catalyzing the hydrolysis/condensation reaction of the silane copolymer. Optionally there may be included in the composition antioxidants, silanol condensation catalysts, organic halogen containing flame retardant compounds and other conventional compounding ingredients.
