Product Introduction
PLG Series Ultra-Lightweight High Alumina Bubble Heat-Insulating Refractory Bricks
Superior Thermal Performance & Energy Efficiency for Industrial Applications
Hubei Zhongnai New Material Technology Co., Ltd.
Advanced Material Technology
Our PLG series high-strength high alumina bubble heat-insulating refractory bricks represent cutting-edge thermal insulation technology. Manufactured using premium bleached alumina beads and advanced forming techniques, these bricks deliver exceptional performance in high-temperature industrial applications.
- Ultra-low thermal conductivity (0.17-0.50 W/mK)
- Lightweight design (0.4-1.0 g/cm³ bulk density)
- High-temperature resistance up to 1400°C
- Excellent structural integrity and durability
- Superior energy efficiency and cost savings
Key Performance Benefits
The unique bubble alumina structure provides exceptional thermal insulation while maintaining structural strength. The closed-cell porosity design minimises heat transfer through conduction, convection, and radiation mechanisms.
- Energy savings up to 30% compared to traditional refractories
- Reduced furnace heat-up and cool-down times
- Lower external surface temperatures
- Enhanced thermal shock resistance
- Minimal linear shrinkage at operating temperatures
