Carbon and Graphite Components for High Temperature Mechanical Applications

Mersen has developed a comprehensive range of mechanical and friction components manufactured using its carbon, composite and graphite materials.

• Carbon and graphite bearings, seals and vanes (guiding and sealing purposes in pumps and valves)
• Dynamic sealing (seal systems for rotary shaft of fans, extractors, turbo-compressors, driers, water turbines)

In mechanical and friction applications, carbonaceous materials are superior to others and reduce costs by eliminating the need for lubrication. 

• At a high temperature: their thermal stability and self-lubricating properties make them ideally suited for use at temperatures above 150 °C, in applications unsuitable for standard lubricants.
• When lubricants are prohibited: certain processes prohibit the use of lubricants: Food preparation, pharmaceutical, and textile applications
• In corrosive environments: the chemical inertia and corrosion resistance of these components allow their use in the most demanding environments.
• When access to moving parts is difficult: in cases where maintenance and lubrication of inaccessible elements is problematic, choosing a solution with carbon or graphite components overcomes these constraints.
• When weight is critical: the density of carbon or graphite components ranges between 1.5 and 2.5 g/cc, much lower than metals.
