PTFE heat shrink tubing has a very high continuous use temperature (260°C), and outstanding chemical resistance. Combining this with a lower melt temperature material (FEP) on the inside makes the only high temperature adhesive lined heat shrink tubing on the market. It is available in 2:1 shrink ratio, and meets or exceeds the most stringent commercial (UL VW-1, UL 910, NFPA262) and military standards (AMS-DTL-23053/12).
Continuous operating temperature -454°F to 500°F (-270°C to 260°C)
Outstanding resistance to almost any chemical known (exceptions: alkali metals in molten state, fluorine gas at high temperatures, chlorine trifluoride).
