Thermiculite 894 is a highly specialised sealing solution within the Thermiculite range, developed for critical service in extreme industrial conditions. Unlike conventional packing, this flexible gasket material maintains performance under severe thermal and chemical stress, offering dependable sealing where other products fail.
Manufactured using Flexitallic’s advanced Thermiculite technology, 894 is created by over-knitting strips of Thermiculite foil with ultra-fine Inconel 600 wire (0.09mm diameter). These reinforced strips are then braided together to form a robust square-section material, supplied in continuous coil form. This unique construction ensures durability, thermal stability, and resistance to oxidation and aggressive media.
