What are the advantages of flexible graphite paper as sealing material?
Graphite paper is now more and more widely used in high-tech electronics industry. With the development of the market, graphite paper has been found new applications, just like flexible graphite paper can be used as sealing materials. So what are the advantages of flexible graphite paper as sealing material? We will give you a detailed analysis:
At present, flexible graphite paper products mainly include packing ring, gasket, general packing, composite plate punched by metal plate, various gaskets made of laminated (bonded) composite plate, etc. they have been widely used in petrochemical, machinery, metallurgy, atomic energy, electric power and other occupations, with excellent corrosion resistance, high temperature resistance, shrinkage and recovery Excellent gentle stress and self-lubricating properties.
Traditional sealing materials are mainly made of asbestos, rubber, cellulose and their composites. However, with the development of industry, flexible graphite paper as sealing materials began to be widely used. The available temperature scale of flexible graphite paper is wide, which can reach 200 ~ 450 ℃ in air and 3000 ℃ in vacuum or reducing atmosphere, and the coefficient of thermal expansion is small. It does not brittleness and crack at low temperature and soften at high temperature. These are conditions that traditional sealing materials do not have. Therefore, flexible graphite paper is descripted as “sealing king”.
