All the material are high purity graphite and fine-grain, as a graphite manufacturer who can provide stable supply for big customer, we have uniform shaped graphite rods and graphite blocks in stock all the time.
Isostatic graphite refers to a graphite material obtained by pressing a high-purity graphite powder in a sealed liquid environment at a normal temperature and transferring the powder by ultra-high pressure. Because the pressure in the liquid is equal on each side, it is called cold isostatic pressing. The shaped graphite has the same performance values in different directions.
