A unique microstructure…

CALCARB® CBCF is made up of carbon fibres measuring just a few millimetres in length, emanating from rayon fibres. These fibres are interconnected in a matrix produced by the carbonisation of phenolic resin. The material is then vacuum-treated at temperatures above 2,000°C to ensure its temperature stability and the absence of outgassing.
As a benchmark, the material contains no more than 500 ppm of impurities. Impurity levels below 20 ppm can be achieved through a halogenpurification process.
For extreme insulation performance…
CALCARB® provides the best thermal insulation properties at a high temperature, making it the material of choice among our customers concerned about the energy efficiency of their process.
Density and grade differences are used to modulate the material's thermal characteristics:
CALCARB® CBCF 14VF-2000 for unparalleled insulation performance
CALCARB® CBCF 18-2000 or CBCF 25-2000 for modulating between insulation and gas permeability

Optimising the efficiency of your processes…
CALCARB® rigid insulation is much easier to machine than other high temperature insulation materials. Its homogeneity, combined with its ability to be machined into very complex shapes, enables precise thermal gradient control in high temperature processes.
Standard dimensions:
Plates up to 160 x 1,500 x 1,500 mm
Cylinders up to Æ 1,100 mm

Extended service life, even in the most aggressive environments.
Mersen has developed a complete range of processes designed to reinforce the resistance of CALCARB® CBCF in aggressive environments:
Pyrocarbon infiltration-CVI protects the material from the action of reactive gases to its core.
A unique development now allows the CALCARB® insulation using silicon carbide SiC-CVI to reduce the felt's reactivity tohydrogen above 1,000°C.
To ensure gas impermeability and significantly reduce the generation of dust through erosion,CALCARB® can be surface coated by Calfoil,Calcoat and Calcoat CVD processes.

About us

Company details

Close to you with the level of expertise and service to increase your performance.

Mersen is a leading global manufacturer of fine grain isostatic graphite, highly involved in the continuous casting market. Beside the quality and the high product performance that you can expect from a market leader, our customers appreciate Mersen’s dense both industrial and commercial network, erected to be reactive and close to them.

Mersen plants are certified ISO9001 version 2000 for the manufacture of graphite blocks, machining dies and crucibles.

Harsh conditions? Challenging shapes? We just love them !

The graphite produced by Mersen is widely used in continuous casting of copper alloys, precious metals, grey cast iron or aluminium. The isostatic graphite produced by Mersen is particularly effective in difficult conditions of use encountered in casting shapes such as strips, billets, rods, tubes or custom sections. Facing issues with your actual solution or looking for better performance? Come and see us on the booth 10G39 Hall 10 !

Stay one step ahead with Mersen GRAPHITE

Based on its expertise, Mersen is able to propose to you the best characteristics required by the continuous casting process, namely: a high thermal conductivity associated with a high resistance to wear.
The grades of graphite are permanently developed and improved jointly with the machine manufacturers, the end users and the most well-known union founders.

Mersen will be pleased to welcome you on the booth 10G39 Hall 10, to talk about your process and how we can support.
