Abstract

Glass fibres which are distinguished by either greatly reduced carcinogenicity have an average fibre diameter of <8 µm, preferably ,3µm, with more than 10% of the fibres having a diameter of ,3µm. The types of glass used for producing these fibres are characterised by containing the following compounds in the proportions shown in mol-%:

55-70 % SiO2, 0-5 % B2O3, 0-3 % Al2O3, 0-6 % TiO2, 0-2 % iron oxides 0-5 % MgO, 8-24 % CaO, 10-20 % Na2O, 0-5 % K2O and 0-2 % fluoride.
