ABSTRACT:
Automotive ignition wire with a high temperature rating, excellent electrical insulating properties, heat resistance, oil resistance and abrasion resistance is described. The wire utilizes a conductor made up of either a helically wound metal conductor on a radio frequency insulating polymer overcoated on a polymer adhesive layer on a glass fiber bundle; or a glass fiber-cotton fiber braid on a graphite impregnated glass layer. Overcoating either one of the conductors is a semiconducting polymer layer, an ethylene-propylene-diene monomer containing polymer layer optionally overcoated with a glass braid layer and a polymer jacket material. The polymer jacket material comprises a polymeric mixture of ethylene vinyl acetate and ethylene-propylene-diene monomer stabilized with a mixture of a phenolic antioxidant and a metal salt antioxidant.
