What are the properties of phlogopite mica?
Phlogopite mica seals are suitable for extreme thermal applications, with a service temperature range from -200 to 1000 °C and a working pressure up to 60 bar. They are chemically resistant and are excellent for sealing in high-temperature environments such as furnace flue gases. Phlogopite mica offers high aging resistance and is particularly resilient against aggressive media.
