GRAFKOTE® U.S. PATENT No. 5,198,063
GRAFTECH (UCAR) GRAFOIL GT™B with corrosion inhibitor.
Flexible graphite gasket material with a strong, thin polymer coating (th. 0,03 mm). The GRAFKOTE sheet is manufactured with no binders, therefore giving it the excellent thermal stability, thermal conductivity and chemical inertness inherent to graphite. The thin polymer coating enhances the product handleability and durability and anti-stick effect.
GRAFKOTE replaces all jointings materials in its class.
No aging.

Max. permanent operating temp. - innert:
 +850 °C
Max. operating pressure:
 80 bar
Compressibility (ASTM F 36 A):
 40 %
Backspring:
 15 %
Leachable chlorides and fluorides (ASTM F-1277):
 10 ppm
Foil density:
 1,12 g/cm3
Sheet dimensions: 1000 x 1000 mm
  
Thicknesses: 1,5 and 2,0 mm
  

The unique properties of GRAFKOTE along with the strength of the polymer coating make it an excellent gasketing material. In most of industrial applications replaces all the asbestos and non-asbestos fiber reinforced jointings. At higher temperatures the polymer coating became carbonized and hasn't any influence on chemical resistance and properties of jointing. Good quality/price rate.
