Heat & High Temperature Resistant PTFE Coated Fiberglass Gasket Seal Tape
Heat & High Temperatureresistant PTFE Coated Fiberglass Tape
This heat and high temperature resistant tape provides high temperature and chemical resistance along with thermal insulating properties. Resistant to almost all solvents, caustics and acids.
This heat resistant tape is PTFE coated, and is used as a gasket and seal material for a variety of mechanical surfaces. Also as a chemically resistant insulation material for wire, cable, hose, tube and pipe carrying high or low temperature liquids or gases. Makes a good gasket seal against steam, water, gases and other fluids.
The base fiberglass fabric is rated to 1200°F / 648°C while the PTFE melting point is 620°F / 327°C.
Available in 1/16", 1/8" and 3/16" thickness and 0.5" to 6" widths.
This heat resistant tape is available in Plain and Drop Warp Styles. Drop Warp tape has several of the center lengthwise yarns missing during weaving, and allows the tape to be easily used for bolt-hole applications (sometimes called a ladder tape or bolt-hole style tape).
The PTFE is applied to the tape by dipping the tape through an immersion tank of liquid PTFE dispersion. The tape is then air dried as it leaves the dip tank. The result is a PTFE coating on the tape which is soft, robust and flexible; however, it can be abrasively removed from the tape with aggressive fingernail scraping, resulting in a thinner and thinner layer of PTFE remaining with each pass. The PTFE also causes the yarns to be sealed and the small gaps between the yarns filled, resulting in an almost air-tight / liquid-tight tape.
