High silica fiber is a kind of inorganic fiber that is characterized by its resistance to high temperatures.Its softening point approaches 1700℃ and can be used at 900℃ for a long time.
With resistance to temperature up to approximately 1000℃, this fiber is used for the production of fireproof protective mats, fireproof curtains and fire blankets. It is also used as protective material for welding, a filter for molten metal, for dust collection in high temperature gas media, and filtration in high temperature liquids etc.
Introduction:
Silica Fiberglass Needled Felt is made from silica fiberglass chopped strand through needling process.Silica fiberglass randomly distributed in 3-D structure. It has properties of small needing 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.
