Abstract:
A low viscosity E-glass composition including SiO2 in an amount ranging from 52-54 weight percent, Al2O3 in an amount ranging from 12-14 weight percent, F2 in an amount ranging from 0-1.0 weight percent, Fe2O3 in an amount ranging from 0 to 0.8 weight percent, Na2O in an amount ranging from 0-2.0 weight percent, K2O in an amount ranging from 0-2.0 weight percent, CaO in an amount ranging from 16-23 weight percent, MgO in an amount ranging from 0-3.0 weight percent, Li2O in an amount ranging from 0-3.0, TiO2 in an amount ranging from 0-1.5 weight percent, ZnO in an amount ranging from 0-4.0 weight percent, and B2O3 in an amount ranging from 8.0-10 weight percent is provided. The glass composition has a log 3 viscosity temperature between 1750 and 2150° F. and a ΔT temperature greater than 50° F.
