Features for Iso-Molded Graphite

Iso-Molded Graphite, also named Isostatically Pressed Graphites or Isostatic Graphite. It is produced by the method of Cold Isostatic Pressing (CIP). Graphite is iso-statically pressed is because it allows for uniform properties in all grain directions. This differs from extruded which is pushes through a die and has varying properties in different grain directions. Iso-Molded Graphite is used for specific applications where uniform is required.

XRD Graphite obtain a high finished product yield rate due to our unique process and quality control, this enable us to produce high quality consistent graphite.

    Our Iso-molded graphite can be manufactured as blocks and rounds in various sizes and can be purified to less than 20 ppm as per your request. For properties of popular XRD sizes please see table below:
