High-Performance Polycrystalline Mullite Fiber Blanket

Product Introduction

High-Performance Polycrystalline Mullite Fiber Blanket is a premium-grade refractory insulation material manufactured from high-purity alumina and silica through a controlled sol-gel process and high-temperature sintering. The blanket features a uniform polycrystalline microstructure, offering exceptional stability in extreme thermal environments.

With continuous service temperatures up to 1500°C, it provides outstanding thermal shock resistance, low thermal conductivity, and excellent mechanical strength under high-temperature loads. The material is lightweight, non-brittle, and free from shot impurities, ensuring superior insulation efficiency and long-term durability.

High-Performance Polycrystalline Mullite Fiber Blanket is widely used in high-temperature industrial furnaces, petrochemical equipment, heat-treatment systems, energy storage, and other advanced thermal engineering applications requiring reliable, long-lasting insulation.
