Abstract A low-density abrasive product formed of a uniform cross-section lofty web comprised of continuous three- dimensionally undulated inter-engaged autogenously bonded filaments of high yield strength filament-forming material impregnated with a tough adherent binder which adherently bonds the filaments together and also bonds a multitude of abrasive granules uniformly dispersed throughout the web. The abrasive article is made by forming the web by an extrusion process, uniformly coating the filaments of the web with a liquid curable binder resin, depositing the abrasive granules onto the wet coating, curing the first binder coating, applying a second coating of liquid curable binder and then curing the binder.
