In today's advanced high-temperature industrial environments, equipment faces increasingly extreme thermal loads—exceeding 1000?°C in applications such as metallurgy, ceramics, glass melting, and heat treatment. Ordinary insulation materials can't withstand such conditions. That's where CCEWOOL ceramic thermal blanket comes in, offering exceptional heat resistance and thermal stability—perfect for the harshest environments.

What temperature can a ceramic thermal blanket withstand?

Made from premium alumina (Al?O?) and silica (SiO?), CCEWOOL ceramic thermal blankets are crafted via high-temperature electric furnace melting and fiberization. The dense yet flexible fiber structure supports different thermal grades:

Standard grade – up to 1260?°C: Ideal for most industrial furnace linings;

High-alumina grade – up to 1360?°C: Suited for more demanding thermal treatments;

Zircon-enriched grade – up to 1430?°C: Designed for sustained high-temperature exposure and aggressive environments.

Moreover, these blankets exhibit outstanding thermal shock stability—no degradation, crumble, or collapse under rapid heating and cooling cycles.

Why is high temperature resistance so important?

Enhances thermal efficiency

Maintains low thermal conductivity even at high temperatures—effectively reducing heat loss and improving energy savings.

Extends refractories lifespan

Retains structural integrity, resisting degradation and reducing the frequency of repairs.

Ensures operational safety

Remains stable under extreme heat, preventing leaks, damage, or safety incidents.

Adapts to complex geometries

With flexible fiber form, the blanket can be cut and shaped to fit irregular areas, ensuring comprehensive insulation.

CCEWOOL ceramic thermal blankets are widely used in glass furnaces, tunnel kilns, steel heat-treatment furnaces, aluminum melting pots, petrochemical heaters, and more. Customers report consistent high-temperature performance over years of operation—cutting energy costs and maintenance downtime.
