Products Description
 

Eco-Friendly Asbestos-Free Flexible Graphite Gasket

 

Flexible graphite materials consist of sheets, foils, papers, tapes, and strips. These materials are crafted by treating natural graphite flakes with chemical processes and then subjecting them to high - temperature exfoliation. This process creates worm - like graphite structures that have a density of approximately 0.003g/cm³. The expanded graphite is rolled into coils without the use of binders or fillers, ensuring the following characteristics:

 

  • An eco - friendly composition, free from asbestos and other harmful substances
  • A high level of purity, reaching over 99%
  • Resistance to chemicals and corrosion
  • The ability to withstand radiation
  • Thermal stability across a wide range, from - 200°C to +650°C
  • Excellent compression recovery properties
  • Self - lubricating features
  • A gas - tight sealing performance

 

These qualities make our flexible graphite gaskets an ideal choice for low - pressure sealing applications in environmentally sensitive industries. Additionally, composite materials can be made by laminating the graphite with metal substrates.

 

Product Applications:

 

  1. It serves as the core material for packing rings in pumps and valves.
  2. When combined with metal sheets, it forms composite gaskets that can be die - cut into any custom shape.
  3. Thick - cut sheets are used for manufacturing low - pressure seals and high - temperature insulation components.
