Silica Needle Mat

Our Silica Needle Mat is an ultra-high-temperature insulation material composed of high-purity amorphous silica fibers. Through a specialized needling process, these fibers form a flexible, resilient, and uniform mat with exceptional thermal stability. It is specifically engineered for applications where fiberglass or other conventional materials cannot withstand extreme temperatures, offering superior performance in demanding industrial environments.

● Exceptional High-Temperature Resistance: Can withstand continuous operating temperatures up to 1000°C (1832°F) and short-term exposure up to 1200°C (2192°F), with minimal linear shrinkage.
● Ultra-Low Thermal Conductivity: Provides outstanding thermal insulation efficiency at both high and low temperatures, significantly reducing energy consumption.
● Excellent Thermal Shock Resistance: Exhibits remarkable stability and integrity under rapid temperature cycling and extreme thermal gradients.
● High Chemical Purity & Stability: Composed of over 96% silica, it is highly resistant to most corrosive chemicals, molten metal splashes, and oxidation. It remains non-hygroscopic and does not react with many metals and alloys.
● Low Heat Storage & Lightweight: Low heat capacity allows for faster heat-up and cool-down cycles, improving process efficiency. Its lightweight nature facilitates easy handling and installation.
● Excellent Resilience & Flexibility: The needled structure provides good tensile strength and flexibility, allowing it to conform to complex shapes and withstand mechanical vibration without falling apart.
● Non-Combustible & Environmentally Friendly: Classified as a non-combustible material (A1级). It contains no binders, resulting in low smoke emission and no harmful gases when exposed to high heat.

● Metallurgical Industry: Ideal for high-temperature gaskets, expansion joints, furnace door seals, ladle and tundish covers, and backup insulation in iron and steel processing.
● Aerospace & Defense: Fiberglass cotton is used as thermal protection, fire barriers, and insulation in engines, exhaust systems, and testing facilities.
● Ceramic & Glass Manufacturing: Employed in kiln car seals, furnace linings, glass melting tank insulation, and as a separation layer in ceramic firing.
● High-Temperature Furnaces & Heat Treatment: Perfect for lining and sealing vacuum furnaces, electric element furnaces, sintering furnaces, and other high-temperature industrial furnaces.
● Automotive & Petrochemical: Used in high-performance exhaust systems, catalytic converter insulation, and as fireproof protection in critical areas of refineries.
● Power Generation: Insulation for gas turbines, boiler expansion joints, and high-temperature ducting in power plants.
● Fire Protection: Serves as an excellent fire barrier and insulation layer in commercial and industrial building safety systems.
