Abstract
The present invention relates to flame retardant insulation and jacketing compositions useful for wire and cable products which exhibit improved adhesion to the metal conductor. This is achieved by the use of a specific stabilizer package comprised of three specific antioxidants and by varying their relative proportions. The compositions are based on ethylene-vinyl esters and ethylene-alkyl acrylate copolymers and are formulated with a hydrated inorganic filler, an alkoxy silane, a crosslinking agent and the three-component stabilizer package. Antioxidants utilized for the three-component stabilizer package include tetrakis[methylene(3,5-di-tert-butyl-4-hydroxyhydrocinnamate)]methane, pentaerythritol tetrakis(betalaurylthiopropionate) and thiodiethylene bis(3,5-di-tert-butyl-4-hydroxyhydrocinnamate).
