This disclosure, in general, relates to nonwoven abrasive belts including flexible butt joints and methods of making and using such belts and joints.

Nonwoven abrasive belt with flexible joint

Articles and methods regarding the making and use of low-shedding nonwoven abrasive articles, such as abrasive wheels and hand pads, that have a low shed rate and achieve a high grind ratio. The abrasive articles comprise a blend of a plurality of primary abrasive particles and a plurality of reinforcing abrasive particles that is disposed on a nonwoven web substrate. The primary abrasive particles have an average particle size equal to or larger than the average fiber diameter of the substrate fibers, and the reinforcing abrasive particles have an average particle size smaller than the average fiber diameter.

Low-shedding nonwoven abrasive articles

The present disclosure relates to abrasive articles that include abrasive aggregates of silicon carbide with a vitrified bond, and methods of making and using such abrasive articles and abrasive aggregates. In particular, the abrasive aggregates can possess a combination of beneficial properties and comprise a vitreous binder composition having a specific composition, sintering temperature, glass transition temperature, or a combination thereof.

Abrasive articles including aggregates of silicon carbide in a vitrified bond

An abrasive article comprising a nonwoven substrate material having a top surface and a bottom surface; a woven cloth; a thermoplastic fastener; and a plurality of abrasive particles, wherein the cloth layer is adhered to the top surface of the nonwoven substrate material; wherein the thermoplastic fastener is disposed on the cloth, and wherein the plurality of abrasive particles are disposed on at least the bottom surface of the nonwoven abrasive substrate.
