High Temperature, Heat & Chemical Resistant & Thermal
Insulating PTFE Impregnated/Coated Fiberglass Sleeve
Coated Braided Fiberglass Sleeve
550°F / 287°C Continuous Exposure: Higher Intermittent
This high temperature, heat & chemical resistant and thermal insulating PTFE (Teflon® is a branded version of PTFE from DuPont) impregnated/coated fiberglass sleeve 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 PTFE coated fiberglass sleeve is an excellent wire, cable, hose, pipe and tube protective cover providing insulation value, energy savings and personnel protection.
The base fiberglass fabric is rated to 1000°F / 537°C while the PTFE 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 1/16" and 1/8" wall thickness.
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.
