Abstract
Flame retardant compositions useful as insulation for 150° C.-rated wire and cable applications are provided. The compositions of the invention utilize an ethylene-alkyl acrylate copolymer base resin with a two-component stabilizer package consisting of a zinc salt of a mercaptobenzimidazole and an aromatic secondary amine compound. Also, included to achieve the requisite flame retardance, crosslinkability and physical properties are a brominated flame retardant, antimony trioxide, a hydrated inorganic filler and a chemical crosslinking agent.
