Flexitallic Thermiculite® 894

Thermiculite® 894 is made by over-knitting strips of Thermiculite foil with a fine (0.09mm diameter) Inconel 600 wire and then braiding a number of those Thermiculite / Inconel strips to produce a square section sealing material available in continuous coil form.

Thermiculite® 894 is intended for high temperature and / or aggressive media applications where a flexible gasket / packing is required. Such applications include but not limited to oven door seals, very large diameter flanges and in the production of industrial fertilizers.

This material can also be used in conventional high temperature valve stem sealing systems for on-off or isolation valves. Alternatively, as the header rings either side of a conventional valve stem sealing stack it can provide an oxidation barrier for the standard graphite components.
