Standard Sizes and Packaging

 

ADVANTAGES

  • Asbestos-free
  • No respirable fibers
  • No health hazard
  • No aging or embrittlement
  • Non-toxic and suitable for foodstuffs
    and potable water
  • Low chloride content
  • Excellent creep resistance with no hot
    or cold flow
  • Excellent gas and fluids impermeability

APPLICATIONS

  • Elevated service pressure and gasket
    stresses
  • Heat transfer oils
  • Cylinder gaskets
  • Reinforced sealing gaskets spacers
  • Pipework and vessel in the petro-
    chemical industries and power stations
  • Tongue-and-groove
  • Pumps and fittings
  • Unstable flanges with low gasket
    stresses
 
Pure Graphite Sheet
 
Pure Graphite Sheet is made from exfoliated graphite flake and is produced through an extensive calendaring process to give a thin flexible foil with no binder or resins.
