Abstract
An improved multiconductor ribbon cable the conductors having at least two layers of polytetrafluoroethylene (PTFE) insulation, a porous unsintered inner layer, that is, the one closest to the conductors, and an impermeable sintered outer layer. Webs of impermeable sintered PTFE connect the insulated conductors. The process for manufacturing the cable includes embedding the conductors between inner sheets of expanded unsintered PTFE and outer sheets of extruded unsintered PTFE, then compressing the sheets only in the web region to high density, and sintering the webs plus the outer insulation layer.
