Description
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.
Mica gaskets are used in the automotive sector, gas turbines, gas and oil burners, heat exchangers and in other flange connections. Mica gaskets are made from a material which consists of phlogopite mica paper and is waterproofed with a silicone binder.A special heat resistant steel [1.4828] provides mechanical
reinforcement in the form of corrugated metal ring inserts, eyeletsand/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%.
