High-Temperature 1600℃ Alumina Fiber Board For Industrial Furnaces

Engineered for extreme thermal environments, High-Temperature 1600℃ Alumina Fiber Board is a premium insulation solution that combines advanced material science with superior performance. It is composed of high-purity polycrystalline alumina-mullite fibers, formed through an advanced sol-gel process and high-temperature sintering to ensure exceptional thermal and chemical stability.

High-Temperature 1600℃ Alumina Fiber Board delivers outstanding durability under high-temperature conditions, maintaining high mechanical strength and superior dimensional stability even during prolonged use at temperatures up to 1500℃. Its low thermal conductivity and minimal heat storage capacity enable excellent energy efficiency, while its remarkable resistance to thermal shock and chemical erosion ensures long-lasting performance in demanding applications.

As an environmentally friendly material containing no harmful binders or additives, it is widely used in lining systems, backup insulation, and high-temperature processing units across metallurgical, ceramic, glass, and petrochemical industries. Easy to cut and shape for custom installations, it offers a reliable and energy-saving solution for critical high-temperature applications.

Exceptional Heat Resistance: With a maximum service temperature of 1500℃, it operates reliably in demanding high-temperature environments over the long term. Its resistance to high-temperature shrinkage far exceeds that of conventional ceramic fiber products.

Superior Thermal Insulation: Featuring extremely low thermal conductivity and high heat capacity, it effectively blocks heat transfer, significantly reducing energy consumption in industrial kilns and related equipment while improving thermal efficiency.

Durable & Stable Structure: The board boasts a uniform microstructure and strong mechanical strength, along with excellent thermal shock resistance. It resists cracking and spalling, ensuring an extended service life.

Low Heat Capacity & Chemical Resistance: With minimal heat storage, it enables rapid heating and cooling of kilns. Additionally, it demonstrates strong resistance to most chemical substances.

Lining and backup insulation for various industrial kilns (e.g., ceramic sintering kilns, steel heat treatment furnaces)
