FM-HIGH® and Micatherm are the materials which FMI designed and manufactured with a view to meeting the most demanding sealing requirements. Thanks to their chemical formulation, these patented materials, which are available as sheets, fillers for spiral wounds and facing for camprofiles, can be used in all critical applications where other materials fail to ensure the required resistance, durability and reliability up to 1000 °C.

FM-HIGH® and Micatherm are oxidation-free.
