1. Product Overview
The 1600°C polycrystalline mullite ceramic fiber module is a premium high-temperature insulation module designed for industrial furnace lining systems. Manufactured from high-purity alumina (Al₂O₃) through high-temperature melting, fiberizing, and crystallization processes, it forms a stable polycrystalline mullite structure.
Compared with standard ceramic fiber modules, this high temperature ceramic fiber module offers significantly improved thermal stability, reduced shrinkage, and extended service life under extreme conditions up to 1600°C.
It is widely used as a refractory insulation module for furnaces, kilns, and thermal processing equipment, delivering excellent energy efficiency and long-term performance.
2. Structure & Working Principle
This ceramic fiber insulation module is pre-compressed and assembled into block units with anchoring systems. After installation, the modules expand to form a seamless and dense insulation lining.
Key working advantages:
-
Eliminates gaps between modules
-
Reduces heat loss and thermal bridging
-
Enhances furnace sealing performance
-
Improves overall insulation efficiency
The internal porous fiber structure traps air, minimizing heat transfer and improving insulation performance in high temperature environments.
