AUWIN CMC
Flexible Ceramic Fiber Felt-Frax 1430Z-FT
Strong,
flexible, and stretch-resistant
High-purity material for extended lifespan
Ideal for applications requiring flexible fitting and sealing
Auwin FRAX ceramic fiber felt is a premium flexible refractory material made from high-purity ceramic fiber wool and carefully selected binders. Using advanced production technology, this flexible insulation offers excellent tensile strength, low thermal conductivity, and stable high-temperature performance.
Frax 1430Z-FT is a zirconia-enriched ceramic fiber felt designed for ultra-high-temperature applications. With a continuous working temperature of 1350 ℃ and superior thermal stability, it is the perfect choice for demanding furnace and sealing applications.
Features:
• Ultra-High Temperature Resistance: Classification temperature 1430 ℃; continuous use up to 1350 ℃.
• Zirconia-Enriched Formula: Al₂O₃ + SiO₂ + ZrO₂ ≥95% for outstanding high-temperature stability.
• Low Shrinkage: ≤4% linear shrinkage after 24h at classification temperature.
• Excellent Thermal Performance: Thermal conductivity 0.15 W/m·K at 800 ℃, 0.21 W/m·K at 1000 ℃.
• Superior Durability: Strong tensile strength combined with flexibility for long service life.
