1600C Alumina Fiber Board

Product Introduction

1600C Alumina Fiber Board is a premium, high-temperature insulation material engineered for extreme environments. Composed primarily of polycrystalline ceramic fibers with a high-purity mullite structure, it is manufactured through a sol-gel process and high-temperature sintering, ensuring exceptional thermal and chemical stability.

1600C Alumina Fiber Board delivers outstanding performance with its robust texture, high mechanical strength, and superior dimensional stability, capable of prolonged service at 1500°C without deformation or degradation. Its low thermal conductivity and heat storage capacity contribute to excellent energy efficiency, complemented by remarkable resistance to thermal shock and erosion.

As an environmentally friendly solution free from harmful additives, it is widely used as lining, backup insulation, and in thermal processing systems across the metallurgical, ceramic, glass, and petrochemical industries. Easily cut and shaped to meet specific requirements, it is the ideal choice for high-temperature, energy-saving applications
