Construction: Zt-410(graphite sheet jacketet tanged metal) is made by materials of three cascades. A laminated graphite is inserted into a convexo-plane metal frame perforated. It is produced by specially pressing and sticking process. This kind of sheet is be seized of the characteristics such as good compressibility and resilience, small stress relaxation, fine compensation function for uneveness of sealing surfaces and long working life. Normal style: zt-410/304 Zt-410/316 Zt-410/other tanged metal material Technical data: Compressibility: 19-23% Graphite purity: min 99% Chloride content: max 50ppm Temperature: -200 to 550 Pressure: up to 600bar Ph: 0-14 Media: Steam, mineral oils, heat transfer oil, hydraulic oil, fuel, water, seawater, freshwater. Benefit: Permanently elastic, even in hot-cold cycles over the entire temperature range, no aging, no brittleness, no hot or cold flow, long time uniform compressibility and resiliency independent of temperature.
