Graphite Specialties supplies a wide range of components made of high purity graphite, carbon fiber reinforced carbon (SIGRABOND ) and felt (SIGRATHERM) for semiconductor technology, power generation and thermal and power management.
We have developed special grades for all applications mentioned
below in all required sizes and offer all types of graphite materials - isostatic
graphites, extruded and vibration molded graphites, CFC (SIGRABOND),
insulation materials and coatings. All products can be supplied
in highest purity.
