Advanced thermal insulation material for EV battery safety, energy storage fire protection, industrial insulation, and aerospace thermal management.
PANOF Aerogel Felt, also known as Pre-Oxidized Polyacrylonitrile Fiber Aerogel Felt, is an advanced thermal insulation material that combines the exceptional heat resistance of pre-oxidized fibers with the ultra-low thermal conductivity of silica aerogel.
The material features a lightweight porous structure, excellent flexibility, flame resistance, and outstanding thermal insulation performance. As thermal management requirements continue to increase in electric vehicles, energy storage systems, industrial equipment, and aerospace applications, PANOF aerogel felt has emerged as a high-value insulation solution.
PANOF (Pre-Oxidized Polyacrylonitrile Fiber) is an intermediate material used in carbon fiber production. Compared with conventional insulation fibers, PANOF offers:
Because of these properties, PANOF is widely used in fire protection and thermal management systems. When combined with silica aerogel, it creates a next-generation insulation material capable of providing superior thermal protection in demanding environments.
Several manufacturing technologies are commonly used to combine silica aerogel with PANOF fiber mats.
The sol-gel impregnation method is considered the highest-performance manufacturing technology. The PANOF felt is immersed into a silica aerogel precursor solution. The liquid penetrates the fiber network, forming a gel structure inside the material. After aging and drying, a highly integrated aerogel-fiber composite is produced.
Extremely low thermal conductivity
Uniform aerogel distribution
Excellent flexibility retention
Strong bonding between aerogel and fiber
The powder coating method is widely used for large-scale production. Aerogel powder is mixed with a silicone-based binder and sprayed onto the PANOF felt surface. Additional needle-punching processes may be used to improve particle penetration and bonding.
High production efficiency
Lower manufacturing cost
Scalable industrial production
Adjustable insulation performance
Melt impregnation technology is often used when improved mechanical properties are required. Aerogel powder is blended with a thermoplastic resin before being introduced into the PANOF fiber network.
Higher tensile strength
Improved durability
Better structural stability
The sandwich composite structure integrates multiple functional layers into a single insulation system.
