1) Less hairiness, strong insulation, alkali resistance.
2) Elongation within the limits of elasticity and high tensile strength,so it absorbs a lot of impact energy.
3)Inorganic fiber, non-combustible, good chemical resistance.
4) good permeability, no white silk.
5)Not easy to burn, can be fused into glassy beads at high temperature.
6) Good processability, can be made into strands, bundles, felts, fabrics and other different forms of products.
7)Transparent and can transmit light.
8)Fusion with many kinds of resin surface treatment agent.
