Getting Smart with Non-Woven Abrasives  

Traditional covered abrasives are a cloth or paper support that has coarse grain “coated” or smeared on to one side. Nonetheless a non-woven belt is composed of an artificial substrate onto which slurry of resins and abrasive grains are set down. Non-woven abrasives are categorized into two categories, they are either scrim supported, which is also recognized as surface conditioning merchandises or non-scrim backed that is the surface finishing, or open web merchandises.

Surface Conditioning
Scrim backed supplies are manufactured by needling artificial fibers into a woven source of monofilament threads recognized as the scrim. It appears a little bit like burlap. This creates a fuzzy textured substrate on a single side onto that a slurry of resins as well as abrasive grit are deposited.

Surface Finishing
Non-scrim, open web substances is identified by the absenteeism of the woven base or scrim for power. It is more standardized than scrim supported material with the resin plus abrasive grain steadily distributed all over. The nylon or polyester fibers are needled all together to create an open, spongy mesh that is then dipped into the resin as well as abrasive grit blend.
