Micaceous iron oxide (Fe2O3) is a pure, natural product in the oxide class of minerals. Its hardness according to Mohs is 6.0 to 6.5, with a density of 4.8g/cm³. In addition to standard types for heavy-duty corrosion protection, newly developed product types especially well suited for thin-film corrosion protection and also as a zinc dust replacement are available. For the ceramics and plastics industry, we supply micaceous iron oxide as a metallic effect pigment in very coarse, narrow grain size ranges.

GraphTHERM® - graphite optimised for heat conductivity. GraphTHERM® developed by Georg H. Luh GmbH especially for improved heat conductivity enable a thermal conductivity of 20 W/mK or more thanks to their special form. The mechanical properties or processability are not impaired even at a high filling degree of more than 60%. This combination of characteristics makes GraphTHERM® especially well suited for plastics applications. GraphCOND® - graphite optimised for electrical conductivity Special pre-treatment and grinding results in graphite particles that enable an effective electrically conductive network to be created even at a low material proportion. A conductivity of >100 S/cm is possible in plastic. GraphCOND® features convincing properties and is versatile in application, for example in dissipative coatings or highly conductive compounds.

Graphite, like diamond, consists of pure carbon arranged in a hexagonal crystal system. One differentiates between natural and synthetic graphite depending on the extraction or production method. Graphite exhibits a unique combination of material properties due to the special crystalline composition of the layer structure.
