Abstract: A layer composite for a seal includes a planar substrate layer, e.g. a graphite foil layer, and a two-dimensionally contiguous polytetrafluoroethylene cover layer which adheres to a surface of the substrate layer. The polytetrafluoroethylene cover layer contains less than 200 g/m2 of polytetrafluoroethylene. A seal and a method for manufacturing a layer composite are also provided.
