Flexible Graphite Foil

Flexible graphite foil is made of pure expanded natural graphite. It is the best material in sealing applications at high temperature. To meet the increasingly demanding sealing applications in different industrial fields, Ruiyi Seal offers a wide range of flexible graphite foils in roll and in sheet with high purity, low sulfur content and oxidation resistance.

Our flexible graphite foils are widely used in making various gaskets and gasket materials, such as graphite packing ring, corrugated graphite tape, reinforced graphite sheet and gasket, spiral wound gasket, corrugated gasket, kamprofile gasket, double jacketed gasket and heat exchanger gasket, etc. And our graphite foils can also be used as solid lubricant in metal stamping and forming applications, or as heat liner in industry furnaces and other heating devices.
