Classification Temperature: 1600℃
Description: mullite crystal fiber needle-punching blanket is made of pure mullite fiber through double-sided needle-punching. The product does not contain any bond or other compositions. The temperature can reach to 1450℃ for a long time operating. At this temperature for a long time under oxidizing, neutral or more reducing conditions,  mullite crystal fiber needle-punching blanket can still keep its former flexibility, strength, softness and fiber structure. mullite crystal fiber needle-punching blanket has a stronger resistance against acid/alkali-corrosion than common ceramic fiber blanket.
