Extruded Graphite Description
Extruded Graphite is a type of synthetic graphite material that is manufactured by compacting and extruding graphite powder and binders through a mold or die. Extruded Graphite is known for its excellent properties, including high thermal conductivity, low electrical resistance, and resistance to high temperatures and chemical corrosion.
Extruded Graphite can come in various shapes, such as rods, tubes, blocks, and custom profiles, making it versatile for different applications that require these specific forms. Its physical and chemical properties can be tailored by adjusting the composition, grain size, and manufacturing parameters, allowing for customization to meet the requirements of specific industries and processes.
