  • Abrasive support, abrasive article comprising the abrasive support, and method for the production thereof
    Patent number: 10124467
    Abstract: The invention relates to an abrasive support, to an abrasive article comprising such a support, to the method for producing the same, and to the use of the abrasive article. According to at least one embodiment, the abrasive support comprises an impregnated support material based on synthetic fibers. The impregnated support material has at least on one side having a surface roughness Rz of 100 ?m to 500 ?m, and having an Rmax of 250 ?m to 600 ?m. The support has an air permeability of at most 20 l/m2 s.

  • FILTER MATERIAL AND FILTER MATERIAL COMBINATION FOR ISOLATING LIQUIDS, AND FILTER ELEMENTS MANUFACTURED THEREFROM
    Publication number: 20160250574
    Abstract: A filter material for isolating liquids from fluid streams comprises a wetlaid or drylaid non-woven or woven, or an open-cell foam. The two sides of the filter material are impregnated with two different binders in such a way that one side of the filter material has a higher surface energy and thus a shorter drop absorption time than the opposing side.

  • SINGLE OR MULTI-LAYER FILTER MATERIAL AND METHOD FOR THE PRODUCTION THEREOF
    Publication number: 20110290713
    Abstract: The invention relates to a single or multi-layer filter material, comprising at least one layer made of cellulose, glass fiber, synthetic fiber, or a mixture thereof, and saturated with a binding agent made of an epoxy resin and a curing agent. The hardening agent comprises a first hardener cross-linking at a lower temperature, and a second hardener cross-linking at a higher temperature, so that the epoxy resin can be hardened stepwise depending on the temperature.
