Introduction
A 1200°C ceramic fiber blanket is a high-performance thermal insulation material widely used in industrial furnaces, kilns, boilers, and high-temperature equipment. Known for its excellent heat resistance, low thermal conductivity, and lightweight structure, ceramic fiber blanket plays a critical role in improving energy efficiency and reducing operational costs in industrial thermal systems.
In this article, we explore the properties, advantages, applications, and installation considerations of 1200°C ceramic fiber blanket, helping engineers and procurement professionals choose the right insulation solution for high-temperature environments.
What Is a 1200°C Ceramic Fiber Blanket?
A 1200°C ceramic fiber blanket is manufactured from high-purity alumino-silicate fibers produced by melting selected raw materials at extremely high temperatures, followed by fiberization. The fibers are then mechanically needled into a flexible blanket form without the use of binders, ensuring excellent thermal stability.
Typical classification temperature: 1200°C
Maximum recommended continuous use temperature: 1050–1100°C (depending on application conditions)
Key Features and Advantages
1. Excellent Thermal Insulation Performance
Ceramic fiber blanket has very low thermal conductivity, significantly reducing heat loss and improving furnace efficiency. This allows faster heating and cooling cycles compared to traditional refractory materials.
2. Lightweight and Flexible
With a density much lower than refractory bricks or castables, ceramic fiber blanket reduces furnace structure weight and minimizes thermal stress. Its flexibility allows easy installation on curved or irregular surfaces.
3. High Temperature Resistance
The 1200°C ceramic fiber blanket maintains structural integrity and insulation performance under high temperatures, making it suitable for most medium-to-high temperature industrial applications.
4. Energy Saving and Cost Reduction
By reducing heat loss and fuel consumption, ceramic fiber blanket contributes to:
Lower energy costs
Shorter furnace start-up times
Increased productivity
5. Excellent Chemical Stability
Ceramic fiber blanket shows good resistance to most chemicals, except strong alkalis and hydrofluoric acid, ensuring long service life in demanding industrial environments.
