ceramic fiber yarn is manufactured using high-purity alumina-silicate fibers (Al₂O₃ 45-55%, SiO₂ 45-55%), reinforced with either glass filament or stainless steel wire to enhance tensile strength for different application requirements. The product range includes multiple grades to address diverse operational needs:
Standard Ceramic Fibre Yarn (without reinforcement) – For general high-temperature wrapping and stitching
Glass Filament-Reinforced Yarn – Provides electrical insulation and moderate strength
Stainless Steel Wire-Reinforced Yarn – Maximum mechanical strength for load-bearing applications

Product Usage:
Ceramic fiber yarn is utilized across various industries due to its superior properties:
Industrial Heat Insulation: Used for covering and insulating high-temperature pipes, containers, and kilns.
Fire Protection: Used in fire shutters, fire doors, fire suits, and fire blankets.
High-Temperature Filtration: Used in chemical industry purification systems.
Safety and Protective Clothing: Used for making heat-resistant clothing, gloves, and helmets.
Sealing and Gasketing: Used in high-temperature valves and flanges.
Electrical Insulation: Used for covering cables and electrical components
Product Advantages
Temperature Resistance: Continuous use up to 1260°C (2300°F), short-term exposure to 1400°C (2552°F)
✔ Low Thermal Conductivity: 0.12 W/m·K at 600°C, reducing heat loss and improving energy efficiency
✔ Chemical Stability: Resistant to most acids, alkalis, and organic solvents
✔ Flexibility & Strength: Tensile strength up to 150 N/mm² (steel-reinforced version)
✔ Non-Combustible: Meets ASTM E136 and ISO 1182 fire safety standards
✔ Customizable: Available in diameters from 1mm to 6mm, with optional silicone coatings for abrasion resistance
Available in standard spool lengths (500m, 1000m, 2000m), the yarn can be further processed into braided ropes, woven tapes, or sewing threads for specialized applications.
Product technology:
Key steps include:
Raw Material Preparation: High-purity alumina-silica materials are carefully selected to ensure uniformity and purity.
Fiber Formation: The raw materials are converted into fine ceramic fibers through a sol-gel synthesis process.
Reinforcement: The fibers are reinforced with fiberglass filaments or alloy steel wires to enhance strength and durability.
Spinning: The reinforced fibers are spun into yarn using specialized techniques to achieve the desired thickness and strength.
Quality Control: Each batch of yarn undergoes rigorous quality control checks to ensure it meets the highest standards
