Abstract (en)
[origin: WO2013091798A2] The invention relates to an impregnated abrasive base paper produced from fibres and having a weight per unit area of 110 - 360 g/m2, which abrasive base paper is partially sized by means of a synthetic sizing agent. The added quantity of sizing agent amounts to 0.5 % - 3.0 %, relative to the dry fibres, such that the abrasive base paper has a suction height in the longitudinal direction of 2 mm to 70 mm. The abrasive base paper has a tensile stiffness index in the longitudinal direction of 2.0 MNm/kg to 7.0 MNm/kg and a modulus of elasticity in the longitudinal direction of 2000 to 5500 MPa.
