Abstract: Various embodiments disclosed relate to an abrasive sheet. The abrasive sheet includes a first layer including an abrasive major surface and an opposite second layer defining a second major surface. The second major surface includes a plurality of protrusions extending outwardly from the second major surface. The protrusions include a first polymer component having at least one of a Shore A hardness ranging from about 5 to about 100 and a Shore D hardness ranging from about 1 to about 70. The first layer and the second layer are directly joined to each other.

Abstract: A porous coated abrasive article comprises a porous backing having opposed first and second major surfaces, and a porous abrasive layer disposed on the first major surface. The porous backing comprises a porous oriented thermoplastic film. The porous backing has a land portion and openings extending between the first and second major surfaces. Each opening has a respective area at the first surface, wherein the openings have a number density of 5 to 4600 openings per square inch, and wherein the total area of the openings is from 1 to 90 area percent, based on the combined total areas of the land portion and the openings. The porous abrasive layer is disposed on the first major surface of the porous backing. The porous abrasive layer comprises abrasive particles retained in a binder and has an abrading surface opposite the porous backing, and the second major surface of the porous backing and the abrading surface are in fluid communication through at least some of the openings. A method of making the porous coated abrasive article using flame perforation is also disclosed.

Abstract: Various embodiments disclosed relate to an article. The article includes a first layer defining a first major surface of the article. The first layer includes a plurality of protrusions extending outwardly from the first major surface. The protrusions comprise an elastic polymer component. The article further includes a second layer opposite the first layer, which at least partially defines a second major surface of the article. The first layer is disposed over a range of about 5% surface area of the second layer to about 99% surface area of the second layer. The first layer and the second layer are in direct contact.
