Abstract

The glass fibres, which have greatly reduced carcinogeneity, have a mean fibre diameter of <8 mu m, preferably <3 mu m, and more than 10% thereof have a diameter of <3 mu m. In addition, the glasses used to produce these fibres are characterised by the following compounds in the proportions indicated in mol%: 55 - 70% of SiO2, 0 - 5% of B2O3, 0 - 3% of Al2O3, 0 - 6% of TiO2, 0 - 2% of iron oxides, 0 - 5% of MgO, 8 - 24% of CaO, 10 - 20% of Na2O, 0 - 5% of K2O and 0 - 2% of fluoride. e
