Graphite Foil


Graphite foil is produced to give a thin flexible foil with no binder or fibre reinforcement.

Natural Graphite, the raw material is a mineral that is mined in a similar way to coal. It is then chemically treated and processed to form a soft flexible foil. No binder is used in the manufacturing process and so the material has many of the properties of solid graphite and can be used on a wide variety of applications from cryogenics at minus 200ºC to elevated temperatures of 3000ºC. The material also has excellent chemical resistance and is suitable for use with most organic and inorganic chemicals with the exception of strong oxidizing compounds such as nitric or sulphuric acid.
The foil is a non fibrous material and has none of the health or handling problems associated with asbestos.

It is available in a range of thicknesses from 0.2mm and in densities of 0.7 gm/cc and 1 gm/cc and can be supplied in sheet or roll form. The standard grade is 99% minimum purity.
