Abstract:
1. A crosslinkable, flame retardant insulation composition having improved scorch resistance comprising: 1) 20 to 60 wt. % of a base resin selected from the group consisting of ethylene-vinyl carboxylate copolymer, ethylene-alkyl acrylate copolymer and ethylene-alkyl methacrylate copolymer, and having a melt index of 0.1 to 10 g/10 min.; 2) 35 to 75 wt. % hydrated inorganic filler; 3) 0.1 to 2.5 weight percent alkoxysilane coupling agent having 2 or 3 C 4) 0.2 to 4.0 wt. % stabilizer comprising at least one hindered phenol stabilizer selected from the group consisting of 4,4′-methylenebis(2,6-di-t-butylphenol); tetrakis[methylene(3,5-di-t-butyl-4-hydroxyhydrocinnamate)]methane; 3,5-trimethyl-2,4,6-tris(3,5-di-t-butyl-4-hydroxybenzyl)-benzene; 1,3,5-tris(3,5-di-t-butyl-4-hydroxybenzyl)-s-triazine 2,4,6(1H,3H,5H)trione; N,N′-bis[3-(3,5-di-t-butyl-4-hydroxyphenyl)propanyl]-hydrazine; octadecyl 3,5-di-t-butyl-4-hydroxyhydrocinnamate; and thiodiethylene bis(3,5-di-tert-butyl-4-hydroxyhydrocinnamate); and 5) 0.4 to 8.0 wt. % of a crosslinking component comprised of α,α′-bis(t-butylperoxy)diisopropyl benzene and 2,4-diphenyl-4-methyl-1-pentene present at a weight ratio of 10:1 to 1:1.
