Polycrystalline Mullite Fiber Blanket

Description: Polycrystalline Alumina Fiber Blanket is manufactured using the “Sol-Gel” colloidal method to be a micro-crystalline mullite-based high temperature refractory fiber, by a high temperature calcination process. It is made from alumina fiber with double punching and it doesn´t contains additives or other ingredients.Features:l  Excellent stability at high temperature.l  Slight contraction due to heating.l  Low shot content, remarkable insulating and refractory performance.l  Good thermal reflection capacity.l  Low heat storage, low thermal conductivity.l  Uniform distribution of the diameter of the fiber, high tensile strength.l  Good flexibility at high temperatures, excellent thermal shock and mechanical vibration resistance.l  Chemical stability, high resistance to corrosion.Application:l  Furnace hot face lining in high-temperature industriesl  Backup insulationl  Burner block warpsl  Expansion jointsl  Gaskets in furnacesTechnical Data:DescriptionPolycrystalline Mullite Fiber BlanketClassification Temperature (°C)1600Continuous Temperature Use Limit (°C)1500Chemical Composition (%) Al2O371-73SiO227-29Leachable ChloridesTraceColorWhiteDensity (kg/m3)96/128Tensile Strength (kPa)>80Permanent Linear Shrinkage (%)1400(°C) x 24h <1.0Thermal Conductivity (W/m·K) 400°C0.09600°C0.16800°C0.221000°C0.281200°C0.361400°C0.45Specification:NameDensity(g/m3)Temperature(°C)Thickness(mm)Length(mm)Width(m)Polycrystalline Mullite Fiber Blanket100/130160010216000.61100/130160012.5216000.61100/13016002572000.61*Specific products could be made according to customers’requirements.
