1600C Alumina Fiber Blanket For Extreme Temperature Insulation

Product Introduction

1600C Alumina Fiber Blanket for Extreme Temperature Insulation is an advanced refractory insulation material produced through the innovative "Sol-Gel" colloidal process. Subjected to high-temperature calcination, it forms a fine microcrystalline structure abundant in mullite phases. Reinforced by a dual-needling technique, the high-purity alumina fibers attain uniform density and improved mechanical strength. Free of binders, the material ensures high chemical stability and exceptional purity.

These alumina fibers deliver excellent thermal stability, low thermal conductivity, and superior resistance to high temperatures, making them ideally suited for critical insulation applications in extreme conditions. The blanket is particularly recommended for use in kilns, furnaces, and other industrial thermal equipment that demands reliable performance at temperatures up to 1500°C.
