Can graphite be flexible?
Can graphite be flexible?
Flexible graphite, also known as graphite foil, expanded graphite or Grafoil®, is manufactured from expandable flake graphite. Due to its unique properties and conformable nature, flexible graphite is made into the following useful forms: Sheets and laminates (used to make gaskets)
What is graphite gaskets?
Graphite is generally used in high temperature and high pressure environments and commonly finds applications in steam cycling or exhaust applications. These gaskets provide a higher performance seal in these conditions than non-asbestos jointing. Graphite has a low friction surface.
What is a flexible gasket?
The three most common styles of flexible graphite materials we use include: pure graphite sheet; graphite sheet reinforced with a tang core; and laminated graphite sheet reinforced with a stainless steel insert. Flexible graphite gaskets are manufactured from sheet and roll material.
What is grafoil gasket?
GRAFOIL® flexible graphite is a superior performing packing and gasket material. It is the first fluid sealing material made exclusively from natural graphite flake. As a result, its resistance to corrosion, aggressive chemicals, heat and fire make it a critical sealing solution for a variety of applications.
Is grafoil the same as graphite?
The name Grafoil® is the original brand name of flexible graphite owned by GrafTech, a company founded in 1886. Grafoil® material was first introduced by Union Carbide in the 1960s. Flexible graphite is 95% – 99% carbon. Flexible graphite is inert to most chemicals, and resistant to heat up to several thousand degrees.
How is flexible graphite made?
Flexible graphite is made from natural graphite flakes. Following chemical preparation with acids and oxidizing agents, the natural graphite is expanded by a violent heat treatment procedure. Self-bonded by a rolling operation, the expanded graphite particles form a continuous strip, without the addition of a binder.
What is CAF gasket?
CAF/Non Asbestos Gaskets are die cut or circle cut from compressed asbestos fibre / non asbestos jointings which are manufactured from carefully selected fibre intimately blended with suitable heat resistant binders etc. and vulcanised into sheets of homogenous compositions and uniform thickness.
What is PTFE gasket?
Gasket & O-Ring Products Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. PTFE can be modified for use as a gasketing material with strong chemical resistance properties. It can also be machined or molded into almost any shape.
What is another name for gasket?
What is another word for gasket?
Is an O-ring a gasket?
O-rings are circular, ring-shaped pieces that sit in a groove between two (usually cylindrical) parts. Terminology note: Any o-ring can technically be called a gasket since they prevent the transfer of liquid and air, but while o-rings are a specific shape of gasket, any gasket cannot be called an o-ring.
What is the difference between grafoil and graphite?
Graphite is a material that comes in an incredible range of forms and properties. Grafoil is a proprietary, flexible form of graphite for use in applications that benefit from the innate properties of graphite and that flexibility.
What is grafoil sheet?
Graphite Foil sheets or Grafoil sheets are cut from our production rolls and stocked. The sheets are an excellent sealing material for high temperature, high-pressure transfer of liquids, gasses, steam, chemicals, and corrosives.
What kind of gaskets do you use for flexible graphite?
1/8″ Thick Cut Flexible Graphite gaskets for use between 150# piping flanges. Grafoil® Flexible Graphite products are ideal for sealing those difficult high temperature applications, chemical applications, and low bolt load applications. Nothing seals as well as flexible graphite or Grafoil®.
How big are graphite gaskets in grafoil sheets?

LAMINATED SHEETS -Density: 70 lb./ft. 3 sheet used for all fabrications -Nominal Thickness: 1/32″, 1/16″, 1/8″, 1/4″ and up -Size: 24″x24″, 39.4″x39.4″ (MxM),…
Which is the best gasket for high temperature sealing?
Grafoil flexible graphite gaskets provide superior performance in high temperature sealing applications. Flexible graphite Grafoil gaskets roll products are manufactured from pure flexible graphite containing no binders or fillers.
What makes a GTJ grade graphite gasket?
GTJ is a high-purity grade based on Grade GTA. This grade contains phosphorous oxides as an inorganic, nonmetallic, passivating corrosion inhibitor that also increases resistance to oxidation by about 125°F GHP GTB sheet thermally bonded on each side of a 0.0015” (0.0381 mm) thick polymer interlayer.
