Our Black PTFE Coated Fiberglass Tape has a slippery surface and wide temperature range, for use in your most demanding applications.  It is chemical resistant and is commonly used in heat sealing and heat transfer applications, where you do not want the heated and mated surface in direct contact with one another.  It comes with a high temperature silicone adhesive so it stays in place once you apply it.  Temperature range is -90F to +450F.
