This product uses E-glass fiber yarn as raw material(fiber filament diameter is 7~9 microns),a short cut to a length of 6cm to 9cm staple, and then carding resolved and puffed into super fine felt and then continuously quilted by thousands of needles of needing machines. Its main ingredient is silica alumina and calcium oxide. It is rather excellent in heat-resistance, tensile strength, toughness, fire-resistance, corrosion stability, electrical insulation. Its strong features are heat insulation, sound absorption, dust removal efficiency better than weave filter material.
