Lamination of thermoplastic fluorocarbon resins with unsintered, extruded PTFE is accomplished in order to insulate products, such as conductors in the manufacture of multiconductor cable, by drawing the unsintered PTFE containing the product embedded in it pressed against the thermoplastic fluorocarbon resin through a sintering zone to melt the thermoplastic resin and snter the PTFE, thereby laminating the two together. In the preferred arrangement a second PTFE tape, which can be sintered or unsintered tape, is also laminated at the same time to the thermoplastic resin, such that the final product essentially presents PTFE outer surfaces with thermoplastic fluorocarbon resin bonding the layers of PTFE.
