Tubular polymeric composite for articles such as tubing and hoses. The composite is formed of a tubular first layer of a thermoplastic block polyether amide resin (PEBA) filled with a more structured carbon black particulate filler to render it electrically-conductive, and a tubular second layer of a thermoplastic polyamide, polyester, polyolefins, or other thermoplastic resin compatible with the PEBA resin of the first material, and which second material optionally may be filled with a less structured carbon black particulate filler to render it electrically-conductive.
