NA1122
High Performance Steam Service Sheet, NBR Binder
Description and Applications
TEADIT style NA1122 was developed to exhibit superior thermal stability during extreme thermal cycling applications. It is specifically recommended for saturated and superheated steam services but has also proven itself to be very effective in sealing liquid petroleum derivates, ethanol, chemical products and other fluids. Field tests have validated the results found in our laboratories and have confirmed the higher performance capabilities of the NA1122 compressed sheet.
TEADIT style NA1122 is a compressed non-asbestos sheet gasket material produced from a combination of inorganic fibres and special fillers, bonded with nitrile rubber (NBR). It is manufactured through a hot calendar process under rigorous quality control standards that are registered under ISO-9001 certification. TEADIT style NA1122 is also available with wire reinforcement.
