Abstract
A mat material includes glass fibers. The glass fibers include about 52% by weight to about 66% by weight of SiO2, about 9% by weight to about 26% by weight of Al2O2, about 15% by weight to about 27% by weight of CaO, 0% by weight to about 9% by weight of MgO, 0% by weight to about 4% by weight of TiO2, 0% by weight to about 5% by weight of ZnO, and 0% by weight to about 2% by weight of Na2O and K2O in total. The glass fibers are substantially free of B2O3.
