Sonflon 7810 Blue
  • Sonflon 7810 Blue
  • Sonflon 7810 is a structured PTFE - Gasket - Sheet manufactured by a unique process which provides a high level of fibrillation to overcome the creep relaxation and cold flow problems associated with normal (skived or moulded) PTFE sheets. 

    Sonflon 7810 is produced from virgin PTFE resin filled with hollow glass micro spheres.



  • It is suitable for service with a wide variety of aggressive fluids, including hydrocarbons, acids and caustics, solvents,water, steam, hydrogen-peroxide, refrigerants, etc.

  • The high compressibility of Sonflon 7810 makes it particularly suitable for use with stress sensitive and/or fragile flange joints, e.g. glass, ceramics, plastic, etc.

  • The excellent malleability of Sonflon 7810 makes repairing of small damages and/or irregularities of the sealing area (flange surface) unnecessary.

  • Sonflon 7810 is quick and simple to install. The used gasket can be removed easily and without residue.
