　　Natural flake graphite after screening as acid cleaning and in treatment, the treated graphite expansion more than 100 times, flotation was pressed into the graphite paper, that is, flexible graphite

　　flexible graphite is mainly used for sealing industry, flexible graphite sheet is mainly used for electric power, petroleum, chemical industry, flexible graphite paper in these industries is mainly used in machine, pipe, pump, valve seal

　　Graphite foil is a new sealing material foundation, has high temperature resistance, corrosion resistance, radiation resistance, good the electrical conductivity and thermal conductivity, good compression rate, rebound rate and low stress relaxation rate characteristics

　　Graphite foil:

graphite foil and graphite sheet is used for machine sealing,.

　　Graphite tape:

graphite tape is used for thread sealing and sealing flange.

　　Graphite foil with glue:

graphite foil and tape with glue mainly used for thread and flange sealing.
