Polycrystalline Wool Blanket

Features:

Classification Temperature: 1600°C (2912°F)

Chemical Composition: Alumina, Silica

CCEWOOL® Polycrystalline Wool Blanket is a high-performance refractory insulation material designed for extreme-temperature applications typically operating at 1350–1500°C (2462–2732°F). Manufactured through a sol-gel and double-sided needle-punching process, it offers a uniform mullite fiber structure, low shot content, excellent dimensional stability, and low thermal conductivity. Its strength and flexibility also support Fabrication into modules, shaped components, and customized high-temperature parts.

Product Introduction

CCEWOOL®
Polycrystalline Wool Blanket

CCEWOOL® Polycrystalline Wool Blanket (PCW Blanket) is designed for extreme-temperature applications at 1350–1500°C (2462–2732°F). Its sol-gel and double-sided needle-punching processes create a uniform fiber structure with good strength and flexibility.

Its mullite crystalline structure provides excellent dimensional stability, resilience, thermal-shock resistance, and chemical resistance in demanding furnace environments.

Extremely low shot content and uniform fibers help maintain low, stable thermal conductivity, reducing furnace heat loss and improving insulation efficiency.

Its consistent fiber quality and flexibility support Fabrication into shaped components, modules, composite insulation structures, and customized high-temperature parts.

Advantages of CCEWOOL® Polycrystalline Wool Blanket

Ultra-High-Temperature Stability

With approximately 73% Al₂O₃, the blanket maintains structural stability in glass furnaces, ceramic kilns, electric melting furnaces, and other high-temperature applications.

CCEWOOL® Bio Soluble Fiber Bulk

Extremely Low Shot Content

The sol-gel process produces uniform fibers with extremely low shot content, supporting low, stable thermal conductivity throughout long-term service.

CCEWOOL® Bio Soluble Fiber Bulk

Very Low Linear Shrinkage

Its high-purity composition and stable crystalline phase help reduce lining gaps, deformation, and maintenance requirements during continuous high-temperature operation.

CCEWOOL® Bio Soluble Fiber Bulk

Chemical and Thermal-Shock Resistance

The blanket withstands demanding furnace atmospheres and repeated thermal cycling, making it suitable for chemically aggressive applications with frequent temperature changes.
