Schunk Carbon Technology SiC30 – Silicon Carbide

2018-12-14 · SIC30 – SILICON CARBIDE/GRAPHITE COMPOSITE MATERIAL However, in tribological appliions, materials with dry or emergency-running properties – and thus on carbon materi-als – are often indispensable. There is no carbon material that is completely blister resistant. Blistering can be generated with the help of special seal ring tests.

Mechanical Seals

The properties of our premium material, SiC30, are superior to the already outstanding properties of conventional silicon carbide materials, and set new benchmarks. This material coines the favorable emergency operation properties of graphite with the toughness of silicon carbide. This is enabled by an unusual production process in which highly porous electrographite is impregnated with
