Flexible graphite as a sealing material, sealing - quantitative tests on the leakage rate from the user to the manufacturer in technology innovation and test equipment are not well resolved. Foreign attaches great importance to technology research in this area, Germany was in 1995 the development of standards, provides testing technology and equipment graphite, requires nitrogen leakage rate flexible graphite sheet and strip composite board is less than 0.1mg / m * s (DIN28091). Our In this context it should also be more work to sell carbon graphite, to improve product quality and level of use efficiency of the State in flexible graphite sealing material. The main seal is packing rings (direct use of flexible graphite paper pressed), spiral wound gasket, packing and general flatness of asbestos products used in graphite metallic materials, are available flexible graphite instead. Based on excellent performance Pingdu graphite factory, asbestos sealing material Highland flexible graphite material, to a large extent it means a huge potential market of flexible graphite material. Flexible graphite material in the short term can not completely replace asbestos sealing materials, a huge potential market capacity. Pingdu graphite manufacturers, graphite, carbon industry is provided by the North Sea Dragon Sea Dragon Carbon Co., Ltd. Weifang. Weifang Sea Dragon Carbon Co., Ltd. (www.longmentanye.com) strong, credible, Shandong Weifang graphite and carbon products industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead North Sea Dragon carbon industry into the brilliant and you work for a better future!
