MECHA DE FIBRAS DESCONTINUAS DE VIDRO CONTENDO AL2O3 DE ELEVADO CARACTER TEXTIL E RESISTENTE A ALTAS TEMPERATURAS E PRODUTOS FABRICADOS COM A MESMA

摘要

The invention relates to Al2O3-containing and high-temperature resistant glass sliver on silica basis having a highly textile, cotton-like and voluminous character. The invention also relates to glass staple fiber products from said glass sliver and their use. The textile character and high-temperature resistance are obtained in particular by selective acid extraction. The composition of the inventive glass sliver comprises in particular SiO2 as main component and 1-5% (wt.) Al2O3 as subsidiary component.
