The flexible graphite sheet is widely used as sealing material in all kinds of industries,however,it has an advantage which is the metals in contact with the graphite usually get corrosion,and with the time goes by,this situation will be worse and worse.then the sealing effect will be failure,even cause a big accident.So we need to know the why this happen and where is the sulfur from? Firstly ,we need to have a know on the production process of graphite sheet: The raw material to make flexible graphite is natural flake graphite,in general,it is Fixed carbon with >99%,research shows that,the sulfur in the natural graphite is 200ppm below,far less than the flexible graphite (>1000ppm),then we could know that,the sulfur is not from…
Graphite sheet is widely used in the industry of electric power, oil, chemical, instrument, machinery and diamond etc.it’s an ideal new type sealing material and could replace rubber, fluoroplastics and asbestos in using for pipe,pump, valve. With the acceleration of electronic product upgrading,and smaller and smaller and the demand for radiator pipe of high performance electronic devices, the new technology of heat dissipation of electronic products, that is, graphite material heat dissipation has been widely used.this kind of new graphite heat dissipation material take advantage of the heat dissipation efficiency, small footprint, light in weight, heat conduction along the two directions etc. We know that the flexible graphite,like graphite sheet, is made of the natural flake graphite,acturally,the natural graphite need…
Flexible graphite is a soft sheet form of compressed natural graphite made from exfoliated mineral flake(crystalline) graphite. Due to its flexible texture, it is referred to as flexible graphite to distinguish it from other forms of graphite materials: flake graphite, amorphous graphite, artificial graphite (hard graphite), graphite electrodes, graphite/carbon fiber, etc. Sometimes flexible graphite is also referred to by a manufacturer's brand name like grafoil. Flexible graphite sheet is made with pure expanded graphite. standard flexible graphite sheet product has a high purity of 99.0% carbon content. Higher carbon content gives the flexible graphite foil better chemical resistance, better thermal conductivity, and better sealing ability. Standard flexible graphite sheet product suitable for most industry applications. As gasket material, it is…
