The invention provides a brush bristle and a brush roll that exhibit a suitable abrasive force and that can reduce or eliminate the abrasion of a mill roll as much as possible. The brush bristle is for use in a brush roll B configured to scour a mill roll for rolling a metal sheet S, and includes one or more monofilaments 2 made of a thermoplastic resin containing abrasive particles. The abrasive particles have a hardness lower than the hardness of the mill roll, and higher than the hardness of the metal sheet S.

An abrasive particle including a shaped abrasive particle including a body having a plurality of abrasive particles bonded to at least one surface of the body of the shaped abrasive particle.

A polishing or grinding pad with a multilayer reinforcement is provided. In one aspect, a floor polishing or grinding pad assembly employs a flexible pad, at least two reinforcement layers or rings with different characteristics, and multiple floor-contacting tools such as abrasive disks. In another aspect, a workpiece polishing or grinding pad assembly includes a flexible and rotatable pad, a polymeric reinforcement layer coupled to the pad and a metallic reinforcement layer to which are coupled abrasive tools. In yet another aspect, a floor-facing reinforcement is more flexible than a pad-facing reinforcement which is more rigid.

An abrasive article having first and second major surfaces includes a lofty open nonwoven fiber web comprising entangled fibers. The fiber web includes a densified outer layer comprising a portion of nonwoven fiber web proximate to the first major surface. At least a portion the entangled fibers in the densified outer layer are melt-bonded to one another. An abrasive material is coated on the densified outer layer. The abrasive material includes abrasive particles having a median particle diameter D50 in the range of 1 to 15 microns retained in a binder material. The abrasive article has a Stiffness Test force of 0.1 to 5.0 pounds (0.45 to 2.27 kg) or less. The abrasive article can be used to abrade a workpiece.

The present disclosure relates to abrasive buffing articles (abrasive buffs) and methods of making the same. The abrasive buffs include a substrate, such as a fabric, that has been impregnated with an abrasive polymeric composition that includes abrasive particles, such as primary abrasive particles and/or abrasive aggregates, such as spray dried abrasive aggregates. The abrasive buffs are flexible and capable of conforming to and effectively abrading, polishing, and buffing workpieces possessing a complex geometry.

An abrasive tool having a bonded abrasive including a body having abrasive particles contained within a bond material and a barrier layer overlying a portion of the body and configured for removal by hand prior to use.
