FP polycrystalline alumina fiber paper is made primarily from polycrystalline alumina fibers combined with a binder. It features excellent flame retardancy, thermal insulation, electrical insulation, resistance to both high and low temperatures, and outstanding aging resistance. The product is halogen-free, non-toxic, and odorless, with a high dielectric constant that provides effective thermal and fire protection.

It has an extremely low dusting rate. It can be used directly or encapsulated, and is widely applied in thermal insulation, fire protection, and electrical insulation for electrical equipment, electronic products, and battery cells.

Our product models are classified by thickness as follows: FP|003, 006, 008, 010, 020, 030, 040, 050.
