Abstract: The invention relates to an adhesive tape in particular for wrapping cables, consisting of a preferably textile carrier and of a pressure sensitive adhesive, applied on at least one side of the carrier, in the form of a dried polymer dispersion, the polymer having been synthesized from: (a) 70.0 to 90.0 wt % of n-butyl acrylate and/or 2-ethylhexyl acrylate (b) 10.0 to 20.0 wt % of one or more ethylenically unsaturated monomers, where at least 50.0 wt % of the ethylenically unsaturated monomers (monomer (b)) comprises methyl methacrylate (c) 0 to 10.0 wt % of a further ethylenically unsaturated monomer, different from monomer (b) (d) 0 to 5.0 wt % of an ethylenically unsaturated monomer having an acid or acid-anhydride function and the pressure sensitive adhesive comprises between 3 and 20 parts by weight of tackifiers (based on the mass of the dried polymer dispersion), the tackifiers having a softening point of more than 90° C. according to ASTM E29-99 (2009).

Abstract: Adhesive tapes comprise a textile carrier and a pressure-sensitive adhesive, applied on at least one side of the carrier, in the form of a thickened dried polymer dispersion, wherein the unthickened dried polymer dispersion comprises: (a) 30.0 to 98.0 wt % of monomeric acrylates; (b) 0 to 50.0 wt % of ethylenically unsaturated comonomers which are not acrylates; (c) 1.0 to 10.0 wt % of tackifier; and (d) 1.0 to 10.0 wt % of kaolin, wherein a rheological additive is added to the polymer dispersion so that the polymer dispersion has a viscosity before drying of 40 to 100 Pa*s at a shear rate of 10/s and a viscosity of 3000 to 8000 Pa*s at a shear rate of 0.01/s.
