ABSTRACT:
An insect-resistant composition containing at least about 75 percent by weight of a polyethylene, e.g. LDPE, HDPE, or LLDPE, at least about 5 percent by weight, up to an amount approaching about 25 percent by weight of a compatability additive selected from chlorinated polyethylene and ethylene-n-butyl acrylate copolymer, and an insecticidally effective amount, up to about 8 weight percent, of an insecticide, e.g. halopyridyl phosphates. Optionally, the compatibility additive may include carbon black in an amount of about 0.5-7.5 percent by weight of the composition. The composition has utility in being formed into useful articles, especially in wire and cable applications, which are insect resistant substantially for the useful life of the articles.
