High Temperature, Heat & Chemical Resistant PTFE
Impregnated/Coated Fiberglass Plain & Bolt-hole Tape
PTFE Impregnated Coated Fiberglass Plain Bolt-Hole Ladder Tape
High-Temperature PTFE
Coated Fiberglass Tape
550°F / 287°C Continuous Exposure: Higher Intermittent

This high temperature, heat resistant and thermal insulating PTFE (Teflon® is a branded version of PTFE from DuPont) impregnated/coated tape and bolt-hole tape offers the advantage of a non-asbestos material with a higher temperature range and with excellent resistance to almost all solvents, caustics and acids. This high temperature teflon coated tape is used as a gasket and seal material and also as an insulation material for wire, cable, hose, tube and pipe carrying high or low temperature liquids or gases.

The base fiberglass fabric is rated to 1000°F / 537°C while the PTFE melting point is 620°F / 327°C.

The base fiber is manufactured to the specifications of ASTM D-578, ASTM committee D13, and subcommittee D13.18.

Available in 1/16", 1/8" and 3/16" thickness and 0.5" to 6" widths
The high temperature and chemical resistant tape is available in Plain and Bolt-Hole (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).

The PTFE is applied to the sleeve through a proprietary process.

The result is a PTFE impregnation on the sleeve which is soft, robust and flexible; however, it can be abrasively removed from the sleeve 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 mostly filled.
