Abstract
Man-made vitreous fibers have a solubility of pH 4.5 of at least 20 nm per day and a melt viscosity of 10 to 70 poise at 1400° C. Novel fibers contain at least 18% AlO. Particular products include external wall insulation or cladding and pipe sections. A composition for making suitable fibers may be selected by determining solubility at pH 4.5 or in macrophage.
