DuPont Protection Technologies Nomex® Pressboard Type 994-NPT

Type 994-NPT pressboard is available in three thicknesses, ranging from 1.0 to 2.0 mm. The small sheet size previously available for Type 994 (355 x 1500 mm [14 x 59 in.]) limited the applications where this product could be economically applied. DuPont recently completed a new, patent-pending process that enables the production of larger sheets with similar properties to those produced with our original process, which was developed in the 1980s. For these three thicknesses of pressboard, the new sheet size will be 730 x 2200 mm (29 x 86.5 in.).
