Silica fiberglass needled mat


    Made from silica fiberglass chopped strand through carding and needling process. Fiberglass randomly distributed in 3-D structure. It has properties of small small needling hole and high porosity. It widely used as filtration and high temperature insulation material in coom, steel, nonferrous metal and chemical industry. It also used as acoustic, insulation, damping and fire resistant material in motorcycle and automobile industry.
