This product uses E glass fiber roving as the raw material while each strand is chopped into a 2-3 inch fraction via the fiber cutting machine and further decomposed into extreme tiny blanket shape through the cotton carding engine. Subsequently, the needled fabrics are ceaselessly sewn by thousands of needles.
It is characterized by heat-resistance, tensile strength, tenacity fireproofing, anti-erosion, and good electrical insulation. The adoption of extreme tiny E glass fiber followed by particular needling leads to numerous thin holes with the fiberglass blanket so as to provide heat-insulation and sound-absorbency.
