High Performance Graphite and Carbon Solutions in Extreme Environments.

Aerospace Industry

The aerospace industry requires severe safety demands with components that are both reliable and resistant to extreme environments. Graphite is in demand for surface tiles on space shuttles, in nuclear technology as a neutron moderator, and under extreme cold conditions such as in cryogenic applications.
The properties of graphite make it perfect for use in the aerospace industry:
  Can withstand extreme temperatures of up to 3000°C
  Resistance to abrasion.
  High density of the isomolded graphite.
  Self-lubricating properties.
  Stable behaviour and friction coefficient in cryogenic environments.

Graphite & Carbon uses in Recreational Products.

Recreational Productsy

Graphite is used in furnaces as part of the carbon-fibre creation process from raw materials. Graphite blocks are used within the furnace walls due to their resistance to extremely high temperatures. Both rigid and non rigid carbon and graphite felt are used as insulation in these carbon fibre furnaces.
Because of its energy-absorbing quality, graphite is used to develop high performance sports equipment including :
  Golf clubs.
  Tennis racquets.
  Hockey sticks.
  Fishing rods.
  Carbon-ceramic brake discs for bikes and sports cars.
Carbon-fibre has become known for it's exceptional strength while being extremely light-weight. Carbon-fibre has widely been used in a number of applications including :
  Carbon-Fibre Motorcycle body parts.
  F1/Formula1 racing car bodies.
  Mountain and racing bike frames.
