In high-temperature industrial operations, thermal stability is the most critical indicator to evaluate whether an insulation material can operate safely over the long term. When furnace temperatures fluctuate from several hundred degrees to over 1200°C, any material that shrinks, powderizes, or collapses will cause heat leakage, lining damage, and unplanned shutdown risks. Therefore, only a Ceramic Insulation Blanket that maintains long-term structural stability at extreme temperatures can be considered a true solution for demanding thermal systems.
The superior thermal stability of CCEWOOL® Ceramic Insulation Blanket originates from deeply optimized manufacturing technologies:
High-purity alumina & silica raw material system, with impurities strictly controlled below 1%, preventing structural degradation at high temperatures.
Electric-furnace melting and high-speed centrifugal fiberization, producing fine, continuous fibers with ultra-low shot content and strong resistance to thermal shock.
Dual-sided needling process, forming a three-dimensional interlocked fiber network that resists powdering or collapse even under repeated heat cycling above 1000°C.
Intelligent control via our patented “Ceramic Fiber Intelligent Manufacturing Management System V1.0,” ensuring uniform fiber density and strength batch-to-batch, further enhancing thermal stability in extreme working conditions.
CCEWOOL® Ceramic Insulation Blanket has demonstrated exceptional performance in real industrial environments:
No powdering, shrinkage, or structural collapse during long-term high-temperature operation
Withstands frequent furnace cycling without thermal fatigue failure
Maintains tight surface contact, eliminating hot spots and thermal leakage
Significantly reduces maintenance frequency and unplanned shutdowns
Extends overall furnace lining life while improving energy efficiency

In the high-temperature industrial world, ceramic wool blankets are widely used in steelmaking, petrochemical, heat treatment, and power industries for their light weight, low thermal conductivity, and superior insulation performance. Yet one question remains crucial for engineers and operators alike: How long can a ceramic wool blanket actually last? In reality, the lifespan of a […]

In high-temperature industrial environments, corrosive agents are among the biggest threats to the service life of furnace linings. Alkali vapors, slag, acidic fumes, and chlorine-containing gases continuously attack insulation layers, leading to fiber embrittlement, powdering, or spalling. When insulation materials lack corrosion resistance, they not only lose thermal efficiency but also risk structural instability and […]
