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.

Abstract: A hollow-cylindrical heat shield includes at least one graphite foil and at least one fiber structure, preferably a wound fiber structure, disposed on the outer side of the at least one graphite foil. The (wound) fiber structure has a degree of coverage of less than 100%. A high-temperature furnace or gas converter having a heat shield is also provided.
