  • Grafoil® Flexible Graphite Gaskets | Quality Flexible graphite

    Grafoil is manufactured by adding and acid (usually Nucleic or sulfuric) to a ground graphite. The result is that graphite "pops" to many times its original size, into what resembles silver/grey worms. Those flexible graphite worms are then placed into a hopper which feeds a gasket sheeter to produce gasket sheets of flexible graphite.
