SUNTHERM ALWOOL Polycrystalline Alumina Fiber Paper

Product Description:

SUNTHERM ALWOOL polycrystalline alumina fiber paper is manufactured primarily from polycrystalline alumina fibers combined with a binder. It offers excellent flame retardancy, thermal insulation, electrical insulation, resistance to high and low temperatures, and aging durability. The product is halogen-free, non-toxic, and odorless, with a high dielectric constant, providing effective thermal insulation and fire protection. It is easy to cut, process, and has an extremely low dust-release rate. It can be used directly or encapsulated for applications in electrical equipment, electronic products, battery cells, and other fields requiring thermal insulation, fire protection, electrical insulation, and flame retardancy.

According to product thickness, our product models are classified into: AL003, AL006, AL008, AL010, AL020, AL030, AL040, and AL050.
