Hy-7038 Expansion PTFE Self-Adhesive Tape(PTFE)

　

  • Expansion PTFE self-adhesive tape is a white pure PTFE product with low density. It features a perfect flexibility, compressibility, outstanding corrosion resitance, aging resistance, creep resitance, selflubricating, low friction coefficient and high tensile strength. It is an ideal sealing product under low and middle temperature.

  1. Parameters:
    (1) Working temperature: -268℃  to +316℃ 
    (2) Working pressure: 5 to 20MPa
    (3) Working medium:all but element fluorine,fused alkali metal such as metallic lithium,
    chlorine trifluoride and liquid fluorine.

  2. Application:
    (1) On the flange surface and irregular sealing of various (especially non-metal)piping
    and pipe fittings.
    (2) various flange surface sealing on enamel lining,glass lining,plastic lining,rubber 
    lining and impervious graphite lining of column,heat exchanger and reaction kettle.
    (3) Suitable to seal flanges of large diameter vessel with low surface machining precision,
    large uneven area,irregular shape or limited bolt tightening force.
    (4) Sealing for intensively corrosive medium or super pure fluid.
    (5) Seal the stuffing of pump and valves.
