Our most cost effective PTFE Coated Fiberglass Tape has a slippery surface and an aggressive acrylic adhesive, so it is sure to stay in place in your application.  It is chemical resistant and is commonly used in heat sealing, mold release and heat transfer applications, where you do not want the heated and mated surface in direct contact with one another.  Temperature range is -40F to +350F, limited by the acrylic adhesive backing.
