Polycrystalline Fiber Aluminum Fiber Board

Sunrise Polycrystalline Fiber Aluminum Fiber boards are loose cotton, blankets, hard felts, modules, veneer blocks, and vacuum-formed sheets, and special shapes made of alumina fibers with alumina content of more than 72% through different production processes. The products are often used in high-temperature thermal equipment of steel, ceramics, electronics, glass, petrochemical, and other industries.


High strength, low thermal conductivity, excellent thermal shock resistance;
High-temperature resistance, it can be directly used as a hot-face backfire material;
Low linear shrinkage, stable high-temperature performance;
High-temperature corrosion resistance, no wave absorption;
Easy to cut and install.


High temperature experimental electric furnace;
Sintering equipment for lithium battery materials;
