ISOSTATIC GRAPHITE GRAPHILOR®3
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 authorized by TÜV and can withstand extreme temperatures.
Mersen offers 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.
GRAPHILOR®3 XBS
Graphilor®3 XBS (phenolic resin) is suitable for 80% of applications, available up to 220°C and offers excellent corrosion resistance.
GRAPHILOR®3 XC
Graphilor®3 XC (carbon resin) is perfect for very high temperatures up to 430°C.
GRAPHILOR®3 XTH
Graphilor®3 XTH (PTFE resin) is chosen for its high corrosion resistance properties.
GRAPHILOR®3 PROPERTIES
- Excellent refractory qualities and mechanical properties
- Very good thermal conductivity and temperature resistance
- Non-contaminating
- Exceptional corrosion resistance
TEMPERATURE AND LONG-TERM STABILITY
- Highly cross-linked resin (BS)
- Resin treated at high temperature (C)
- PTFE resin (TH)

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 graphitization patent was filed by two engineers working for Société Le Carbone in 1893.
