Abstract: A flexible abrasive article includes a unitary backing having first and second opposed major surfaces and comprising a polyurethane. In some embodiments, the backing has an average thickness of from 4 to 6 mils (102 to 152 microns), a tensile strength of 500 to 3200 psi (3.45 to 22.1 MPa), and an ultimate elongation of 230 to 530 percent. In some embodiments, the flexible abrasive article has a tensile strength of 400 to 2400 psi (2.8 to 16.5 MPa), and a ultimate elongation of 180 to 380 percent. An abrasive layer is disposed on and secured to the unitary backing.

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.
