Is FLANGIFLON PTFE Sealing Tape suitable for use with aggressive chemicals and extreme temperatures?

Yes. FLANGIFLON PTFE Sealing Tape is suitable for use with aggressive chemicals and extreme temperatures. It is chemically resistant across the full pH range (0–14), ensuring compatibility with acids, alkalis, solvents and other aggressive media. Thermally, it performs continuously from −240°C to +260°C, covering cryogenic and high‑temperature applications. Additionally, it is engineered to withstand working pressures up to 250 bar (dependent on temperature), delivering durable, secure sealing in demanding industrial environments such as chemical processing, petrochemical, food production and energy.

Can FLANGIFLON PTFE Sealing Tape maintain a reliable seal at pressures up to 250 bar across varying temperatures and media?

Yes. FLANGIFLON PTFE Sealing Tape is engineered to maintain a reliable seal at pressures up to 250 bar, with the allowable pressure dependent on operating temperature. Its exceptional thermal stability (continuous service from −240°C to +260°C) and full pH resistance (0–14) provide broad compatibility with cryogenic and high‑temperature conditions as well as aggressive media, acids, alkalis and solvents. In practice, sealing performance at the upper pressure limit should be verified for the specific temperature, flange type, surface finish and media involved, but as described FLANGIFLON PTFE Sealing Tape is suitable for demanding industrial applications (chemical, petrochemical, food, energy) where high-pressure, wide‑temperature and chemically aggressive environments are present.
