Another side of the flexible graphite sealing material development, is the development of flexible graphite lower indices. Japanese endemic lowest flexible graphite carbon content of 90 percent, reducing the cost and selling price. In fact, some equipment graphite, such as farm machinery, extensive chemical machinery, no need to use high-grade flexible graphite. Low-grade flexible graphite Pingdu graphite sealing performance is better than asbestos and can meet the technical requirements of Pingdu graphite factory, but cost and low-carbon graphite sold, so that low-end products and strong market competitiveness sweep, thus promoting the development of the industry . With the application of flexible graphite products in modern engineering more widely, world demand for flexible graphite material is growing year by year. Most foreign producers of flexible graphite for automotive engine cylinder head gasket, intake and exhaust ports mats and other seals, followed by the seals petrochemical, chemical, power generation and other sectors. Because of the limitations of domestic asbestos disputed, restricted use of flexible graphite seal on the internal combustion engine, the main market is still in the chemical, petrochemical and power generation industries.
