ePTFE Sealing Tape

FLONSEAL™

About ePTFE Sealing Tape

FLONSEAL™ ePTFE (expanded PolyTetraFluoroEthylene) material is completely chemically inert with a temperature range of -200°C to 230°C (-328°F to 446°F). Since there are no additives or fillers in the raw polymer ePTFE does not age ‘in the field’ and has unlimited shelf life.

Due to its expanded, multi-directional fibre structure FLONSEAL™ ePTFE enjoys excellent compression, adhering perfectly to the contours of the chosen sealing surface. Typical applications for our sealing tape include chemical process plant pipe-work; Oil & Gas pipe flanges where sealing faces can sometimes have quite uneven surfaces; man-way hatches and reaction vessel lids.

As standard, FLONSEAL™ ePTFE sealing tape comes with an adhesive strip on one side for ease of fixing and is supplied on small manageable spools.
