The invention pertains to multi-layer polymeric formulations for protecting or insulating metallic objects, and, more particularly, to an integrated, tri-layer, thin-wall insulation composite, for use in a high temperature, automotive-wire article. The tri-layer design comprises an inner layer of a fluoropolymer, polyether sulfone, polyether-ketone, polyetherimide, or thermoplastic polyester; a middle layer comprising a polyolefin; and an outer layer comprising a fluoropolymer. The inner and outer layers serve to protect the middle polyolefinic layer from degradation. |
