DURABON® baked carbon differs from DIABON® graphite mainly in its low thermal conductivity (4 to 6 W/mK) and great hardness. Compared with graphite, its tensile and flexural strength values are some 20 % higher and its compressive strength is 50 % higher. Like graphite, DURABON hard burned carbon is rendered impermeable by resin impregnation. In this impermeable form, it is used in the construction of thermally insulating, corrosion-resistant linings for columns and vessels, as well as for abrasion-resistant pump components.

Ultrafine-grain graphite for specific applications. Its name is derived from the method of production (isostatically pressed; equal pressure from every side). The main features of isostatic graphite are high strength, high density and an isotropic structure. It is therefore used in all applications where the mechanical properties of conventional graphite are inadequate.

Details on properties, manufacturing, and typical applications of isostatic graphite can be found under SIGRAFINE® Fine grain graphite
