High Silica Fiberglass Roving is a kind of inorganic fiber, which is drew and winded from glass marbles through a system of Na2O-B2O3-SiO2. It is widely used for the high temperature-resistance insulation materials, high temperature-proof materials, high temperature gas and liquid-filtration materials and the thermal insulation of spacecrafts and so on. Continuous Roving, Staple Roving and Chop Roving are included. 
 "High-silica" glass fiber is a high-temperature inorganic fiber, softening point close to 1700 ℃, 900 ℃ environment in the long term use, can be used for spacecraft thermal protection, ablative materials, high temperature insulation fireproofing materials, high temperature insulation materials etc., can be made into a variety of products. Continuous high-silica glass fibers can be used for weaving, sewing, winding, short and cutting technology, the high-insulation, thermal insulation and modern protective equipment, such as three-dimensional fabric, casing, chopped yarn, yarn length, suture, and by pad special surface treatment of the sewing thread, rope high-silica glass fiber products.
