Graphite Gaskets

详情

The graphite gasket is consist of alone expanded graphite or expanded graphite with metal reinforcement. the expanded graphite is produced by high temperature, high pressure, and sulphuric acid from natural graphite. the usual density of expanded graphite is for sealing industry is around 1.3 g /cm3. the expanded graphite is possible to use from ***0T up to **0″C and pressure according to reinforced and others influence according to the producer of sheets. the same as in all others industries can not be absolute purity of the material, so also in the sealing industry is existing only technical purity of graphite. thats why the most common amount of graphite is *9″,*1 and this purity called industrially purity. for example for the nuclear power plant is used graphite with purity *9,7% and this purity called atomic purity. the sealing effect is depending on the purity of graphite. the rest are active and passive ashes.
