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)

applications

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.
