The Role of Flexible Graphite Foil in The Sealing Industry

Flexible graphite Paper, Foil, Sheet and Tape has an important role in the sealing industry, mainly used in the field of industrial sealing, especially in the mechanical sealing of pipelines, pumps, valves and other equipment.

Flexible graphite paper has good sealing performance and easy to cut characteristics, can be processed into various graphite seals, such as graphite filling rings, graphite gaskets, etc., for mechanical sealing

 Characteristics of flexible graphite paper( Graphite Tape, Graphite Foil, Graphite Sheet)

 1. Flexibility and compression rebound: Flexible graphite paper retains the excellent physical and mechanical properties of graphite materials, with good flexibility and compression rebound properties, which makes it excellent in sealing applications.

2. Cold and heat resistance: flexible graphite paper is not brittle at low temperatures, not soft at high temperatures, showing excellent cold and heat resistance properties, suitable for various temperature ranges of working environments

3. Antioxidant ability: Although flexible graphite paper in the oxygen environment has a certain high temperature resistance and antioxidant ability, but its tolerance temperature is usually not more than 450 ℃, after more than 750 ℃ will quickly oxidize, resulting in a decrease in performance.

4. Application Scenes for Flexible Graphite Paper

• Sealing gaskets: Flexible graphite paper can be made of sealing gaskets, widely used in a variety of pipes, valves and other flange connections. These gaskets are made by molding or stamping, suitable for different specifications and models of equipment

•  Winding mat: flexible graphite tape and V-shaped or W-shaped metal tape made of winding mat, with excellent resistance to high and low temperatures, corrosion resistance and sealing effect, especially suitable for high temperature, high pressure conditions

Process and material properties

Flexible graphite paper is processed by chemical treatment, high temperature expansion after pressing, and has the advantages of high temperature resistance, corrosion resistance, and good elasticity. These characteristics make flexible graphite paper in the sealing industry has a wide
