Silica Needled Mat
Silica needled mat is made from silica chopped strand 
through carding and needling process. The silica fiber randomly distributed in 3-D structure. It has properties
of small needling hole and high porosity and were widely used as filtration and high temperature insulation material
in steel, nonferrous metal and chemical industry and could
be used acoustic insulation, damping and fire resistant material in motorcycle and automobile industry.
