Abstract (en)
[origin: EP0379633A2] An abrasive having abrasive particles, such as corundum, a binder, which is a curable organic or inorganic system, for example a plastic, such as phenol resin, and fillers having abrasive activities. The abrasive material consisting of abrasive particles, binder and the fillers is present on a flexible support which is formed by a nonwoven. Novel economical fillers having low toxicity are introduced into the abrasive, i.e. metal complex salts having the following composition: uM1 . vM2 . wHal . xChal . zPh in which M1 denotes a pure metal or a mixture of alkali metal, alkaline earth metal and/or Al, M2 denotes a pure metal or a mixture of Zn, Mn and Fe, except for Fe as a chloride, Hal denotes pure halogen or a mixture of F, Cl, Br and I, Chal denotes chalcogenides, O and/or S, Ph denotes phosphate or phosphates having a higher degree of condensation, PrOs (r = 1 - 10, preferably 1 - 2, s = 4 - 20, preferably 4 - 7), u, v, w, x or z denotes 0 - 95% and the sum of u and v is 1 - 95%, preferably 20 - 80%, and the sum of w, x and z is 1 - 95%, preferably 20 - 80%, and the sum of u, v, w, x and z is 100%. These fillers are sintered or fused with one another.
