<p>The preparation of glass fibre granules is carried out by mixing cut glass fibres, sized using a size comprising an organosilane, in the presence of 10 to 25 % water for a sufficient time such that the density increases by at least 67 % using a single mixing device which mixes the fibres or granules constantly at the same frequency. The preparation of glass fibre granules is carried out by mixing cut glass fibres, sized using a size comprising an organosilane, in the presence of 10 to 25 % water for a sufficient time such that the density increases by at least 67 % using a single mixing device which mixes the fibres or granules constantly at the same frequency. After drying, the final granules formed contain at least 95 wt.- % glass. A tackifying agent is in contact with the glass fibres at the latest during the mixing. Independent claims are also included for: (a) Glass fibre granules, with a diameter of between 1 and 10 mm and comprising 50,000 to 500,000 glass filaments, obtained by this method; (b) utilization of these granules for reinforcing a thermoplastic.</p> |
