High Temperature, Heat & Chemical Resistant PTFE
Impregnated / Coated Fiberglass Fabric Cloth
550°F / 287°C Continuous Exposure: Higher Intermittent
This high temperature, heat resistant and chemical resistant PTFE impregnated/coated fiberglass fabric offers the advantage of a non-asbestos material with a higher temperature range and with excellent resistance to almost all solvents, caustics and acids.
The base fiberglass fabric is rated to 1000°F / 537°C, while the PTFE (Teflon® is a branded version of PTFE from DuPont) coating 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 5 weights / thicknesses, in roll widths of 40" and 60", and in roll lengths of 50 yards
The PTFE is applied to the fabric through a proprietary process.
The result is a PTFE impregnation on the fabric 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.
