GASKET MATERIALS – METALLIC
Expanded mineral graphite with tanged stainless steel 316 reinforcement.
Stainless Steel 316 sheet allows the material to achieve substantially higher dynamic loading giving it a high blow out resistance and mechanical strength. The insertion also allows for better handling.

Pure expanded mineral graphite products provides an excellent gasket material for high temperature, high pressure applications or for applications where the gasket width is relatively narrow. The material is resistant to most organic and inorganic acids and is suitable to seal a very wide range of media. It is almost completely impermeable to gases and fluids and is commonly used in very demanding application where low emission is paramount. The material have no ageing or embrittlement problems common with elastomeric based materials and displays long term stability of compressibility and recovery over a wide temperature range. Graphite however is not suitable for use with very strong oxidising compounds like highly concentrated nitric acid or chromic acid
