Graphite Specialties
The range of graphite specialties provides an extensive spectrum of materials - from isostatically pressed, extruded, die-molded, vibration-molded and expanded graphite, carbon and graphite felt to carbon fiber-reinforced carbon.
The SGL Group constructs and processes complex components from these materials. Finishing processes, such as coatings, impregnation and cleaning round off the product portfolio.
