Calcarb: Rigid carbon insulation

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

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

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.
