Sonflon 7800 White
  • Sonflon 7800 White
  • Sonflon 7800 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 7800 is produced from virgin PTFE resin filled with Barium Sulfate. 



  • Universal gasket sheet for all applications. It is suitable for all types of flanges, nearly all media, and a broad temperature range and even for applications with the toughest demands on purity. It is inherently clean and non-toxic.

  • Sonflon 7800 is suitable for service with a wide variety of aggressive fluids, including hydrocarbons, moderate acids and strong caustics, solvents, water, steam, hydrogen-peroxide, refrigerants, etc.

  • The high purity of this gasket sheet makes it excellently suitable for the food and pharmaceutical industry.

  • Sonflon 7800 is not subject to ageing or weathering. It can be stored indefinitely.
