high silica leaching

The term high silica can be used to describe any high-purity glass. However, for use in reinforced plastics, we shall define high silica as a high-purity glass of 95%-plus punty SiO 2 produced by a leaching process. High-silica fibers and fabrics are flexible materials that are similar in appearance to—and produced from—fiberglass. Get price
