Core Features
Our Mullite Mortar delivers outstanding advantages:
- Ultra-high refractoriness: Continuous service temperature up to 1650°C, short-term up to 1800°C
- Exceptional bonding performance: Bonding strength ≥4MPa at 1200°C ensures structural stability
- Superior thermal shock resistance: Withstands 20+ rapid thermal cycles
- Low shrinkage rate: Linear change only +1% to -3% after heat treatment at 1300°C
- Easy application: 4-6 hour initial setting time provides sufficient working window
Mullite Mortar perfectly combines high-temperature performance with construction convenience.
