Nano Thermal Insulation Sealing Mix is a newly developed high-performance refractory insulation material, independently developed by our company. Based on inorganically bonded foamed kaolin, it significantly lowers exterior temperatures by over 30°C at the same thickness, reduces insulation weight, and extends service life. Unlike conventional microporous materials, it offers both exceptional thermal insulation and long-term durability under extreme temperatures—delivering reliable energy savings and performance.
Nano Thermal Insulation Sealing Mix is versatile and works in many types of industrial furnaces, including:
Can typically reduce furnace roof temperature by over 30°C, helping to save energy and reduce consumption.
With lower thermal conductivity, it better resists heat transfer by convection and radiation.
The structure is compact and tightly sealed, enhancing the furnace roof’s airtightness.
Improved long-term safety of the furnace roof.
The product withstands high temperatures for extended periods without significant shrinkage or powdering,
effectively preventing issues such as “hot spots” or “cracking” on the furnace roof, thereby increasing overall safety.
Maintenance-free and extended service life.
Made entirely from inorganic materials, it resists aging and degradation.
With a long lifespan, the product can operate maintenance-free during its service period,
reducing the frequency, labor, and cost of furnace roof repairs.
