The main characteristics of flexible graphite are as follows:
1.excellent heat resistance and cold resistance. The physical properties offlexible graphite can be applied to about 600 ℃ in air, from ultra low temperature of -270 C to high temperature of 3650 ( in non oxidation gas);
2.high rebound rate. When the shaft or shaft sleeve is radial circular runout due to eccentric manufacturing and installation, it has the floatingfunction to meet the requirements.Even if the graphite shows cracks, itcan be well closed, and then the binding is tight to avoid leakage.
3.good self lubrication. Flexible graphite, like natural graphite, slips easilyunder the action of external force, so it has lubrication, good wear reduction and small friction coefficient;
4.excellent chemical corrosion resistance.Besides corrosion in strongoxidizing medium such as nitric acid and concentrated sulfuric acid,flexible graphite has little corrosion in other acids, bases and solvents.
