INTRODUCTION . Chemically, NOMEX paper is an aromatic polyamide and is generally known as an aramid. The molecular structure of the material is particularly stable and the properties of TECHNICAL . NOMEX paper are a consequence of this. data SHEET . NOMEX meta-aramid (metaphenyleneisophthalamide). During the papermaking process, the floc, which are longer than the fibrids, align themselves The paper is produced from two forms of the with the direction of the paper coming off the aramid polymer. Small fibrous binder particles machine. There is therefore a significant fibrids are derived directly from the polymer difference in mechanical properties of NOMEX . under high shear conditions. These are mixed paper in the Machine Direction MD and the with short fibres floc which are cut to Cross Direction XD. Mechanical properties length from a fibre filament. are thus quoted for the two directions. Commercial production of NOMEX paper was started in 1967 at the Spruance Plant located Fibrid Floc in Richmond, Virginia (USA).
