Gaskets for high temperature applications. 
The term Mica describes a group of minerals which have excellent fissility properties due to their silicate layer lattice. Mica has a lamellar non-fibrous structure and has been developed for manufacturing of gaskets for high temperature applications. A special heat resistant steel [1.4828] provides mechanical reinforcement in the form of corrugated metal ring inserts, eyelets and/or sheet reinforcement inserts. Both the media resistance of mica as well as the metallic reinforcement and eyelet elements have to be considered for application with aggressive substances. The consicerably low loss of mass during high temperature applications can be demonstrated with the thermogravimetric method. The loss of mass at 800°C is less than 5%.
Application: Use in the area of hot gases specifically flue gas, exhaust fumes and thermal processes. Combustion plants and motors. Non-metallic gaskets for pipeline flanges, device and container flanges.
