Versatile extruded graphite compatible with large sizes. Vibration-molded graphite can also accommodate larger sizes.
Extruded graphite has a larger particle size than isotropic graphite. Therefore, it is inferior in terms of strength, but it also has the advantage of high thermal and electrical conductivity. In addition to its properties, extruded graphite is also easier to process and is more cost-effective. Furthermore, vibration-molded graphite is more isotropic than extruded graphite and can accommodate larger sizes. <Main Features> ◎ High-temperature stability ◎ Chemical resistance ◎ Thermal shock resistance ◎ High conductivity (thermal & electrical) ◎ Machinability ◎ Suitable for large products (especially vibration-molded graphite)
