Extruded netting

Abstract

Support elements, spacers, filter media and filters are provided that are formed from reticular structures, such as nettings or meshes, and may be used in a variety of demanding filter applications that require high resistance to elevated temperatures, corrosive chemical environment and/or oxidative degradation. A reticular structure comprises an array of intersecting fibers coupled to each other. The intersecting fibers comprise a composition comprising a first polyphenylene sulfide (PPS) resin in about 50% to about 90% by weight of the composition and a second PPS resin in about 10% to about 40% by weight of the composition. The first PPS resin has a peak top molecular weight of a main peak component at least about 50% higher than the peak top molecular weight of the main peak component of the second PPS resin. The composition has an oxygen index (OI) of at least about 32.0 volume % O2.
