The Duo-Tape construction begins with bundled, fine strand resistance wire, 37 to 40 gauge, covered with a minimum of 2 layers of high temperature braided AMOX yarn. The insulated resistance wire is then knitted into a serpentine configuration, forming a flat tape. Once the lead wires are attached, most tapes have an additional braided, dielectric protection layer of AMOX yarn for use on conductive (metal) surfaces.
Heating Tape with Adjustable Thermostat Control or Time Percentage Control has a moisture & chemical resistant silicone rubber extruded outer sheath and a fiberglass reinforced serpentine-wound stranded heating element
