Key Features of Kerui Ceramic Blanket 50mm
- Exceptional Heat Resistance
Withstands continuous temperatures up to 1260°C (standard grade) and 1400°C (high-purity grade). - Superior Thermal Insulation
Low thermal conductivity (0.12 W/m·K at 600°C) minimizes heat loss. It improves energy efficiency. - Lightweight & Flexible
Easily cut, wrapped, or shaped around complex geometries (pipes, ducts, irregular surfaces). - Thermal Shock Resistance
Rapid heating/cooling cycles do not cause cracking—unlike brittle refractory materials. - Chemical Stability
Resistant to acids, alkalis, and corrosive gases. It is suitable for harsh industrial environments. - Easy Installation & Handling
Can be installed using anchoring pins, layering, or modular assembly—no specialized tools required. - Eco-Friendly
Low bio-persistence fibers ensure safer handling. This ceramic fiber blanket is help to reduce carbon footprint by lowering energy consumption.
