ISOSTATIC GRAPHITE GRAPHILOR®3
IMPREGNATED GRAPHITE
As a century-old experienced company in manufacturing fine and ultra-fine structured graphite, Mersen has developed its advanced isostatic graphite (grain size of 20 microns): Graphilor®3.
Graphilor® 3 is the only impregnated graphite resulting from the combination between isostatic graphite and a specific resin. It has the highest mechanical properties authorised by TÜV and can withstand extreme temperatures. Mersen offer a range of three Graphilor® 3, based on various impregnations (phenolic, carbon and PTFE) which ensure the imperviousness, the resistance to corrosion and temperature as well as the long-term stability.

Synthetic graphite, the basis of Graphilor
Artificial graphite is manufactured from a mixture graphite, pitch and others. After molding and firing in an inert environment at around 1,000°C, an amorphous and hard intermediate form of carbon is obtained that does not conduct heat or electricity very well.
By heating it to around 3,000°C in the absence of any air, the carbon is purified and crystallized in a mild, greasy form conducting electricity and heat that can withstand chemical corrosion and very high temperatures. This is artificial graphite or electrographite.
Components measuring up to half a cubic meter can be produced. The first graphitisation patent was filed by two engineers working for Société Le Carbone in 1893.
