High-Purity Ceramic Fiber Needle Blanket | 1260°C Grade Refractory Insulation
PRODUCT INTRODUCTION
Professional grade alumina-silicate fiber blanket verified by Lab Report No. WTGZ202502433. Features extreme thermal stability with only -1.5% linear shrinkage at 800°C. Engineered for heavy-duty industrial applications requiring high tensile strength (44 kPa) and low thermal conductivity (0.134 W/m·K).
【Core Technical Data - Verified by National Testing Center】 We provide facts, not just claims. Based on the latest testing from the Zibo Municipal General Institute of Inspection and Metrology:
- Classification Temperature: 1260°C (Standard Grade).
- Thermal Stability: -1.5% Permanent Linear Change after 24 hours at 800°C.
- Insulation Efficiency: Thermal Conductivity is 0.134 W/(m·K) at a mean temperature of 500°C.
- Mechanical Durability: 44 kPa Tensile Strength ensures the blanket stays intact under vibration.
- Material Purity: Low shot content (>0.212mm) of 11.6% for maximum thermal resistance.
- Standard Density: 107 kg/m³ optimized for industrial heat storage.
【Key Industrial Applications】 Designed for environments where standard insulation fails:
- Mining & Heavy Machinery: Heat shields for high-temperature engines and exhaust systems.
- Petrochemical & Power: Lining for boilers, high-temperature pipes, and steam turbines.
- Metallurgy & Kilns: Expansion joint seals and backup insulation for industrial furnaces.
- Composite Systems: The perfect primary layer for "Ceramic Fiber + Aerogel" hybrid insulation solutions.
【Authority & Quality Assurance】
- Certified Testing: Every batch is traceable to official test reports (e.g., No. WTGZ202502433).
- International Standards: Manufacturing follows GB/T 16400-2023 and GB/T 17911-2018 testing protocols.
- Project Reliability: Trusted for mission-critical cooling, such as our composite solution for Brazilian mining equipment operating at constant 800°C.
【Why Choose Our Ceramic Fiber?】 Unlike low-quality alternatives that shrink and crack at high temperatures, our needle-punched blankets maintain their structural integrity. The low shot content means you get more actual fiber per cubic meter, resulting in a lighter, more efficient thermal barrier.
