Lanmar Copper4 PTFE Tape is a non-metallic product. PTFE film is laminated to the fiberglass fabric substrate, rather than the standard dip-coat process. The result is a top working surface that is pinhole-free which permits longer life in application. This specialty PTFE tape is used in many heat sealing applications, and comes with high temperature silicone adhesive with a yellow dimpled release liner.
