P84 Needle Felt Filter Fabric
Engineered for Extreme Heat & Corrosive Environments
P84 Needle Felt
P84 Needle Felt Filter Fabric is a high-performance filtration material made from polyimide fibers. It offers excellent resistance to high temperatures, chemical corrosion, and fine dust filtration, making it ideal for demanding industrial environments.
With its unique trilobal fiber structure, P84 provides superior filtration efficiency and lower emissions compared to conventional filter media.
Features of P84 Filter Fabric
- Excellent heat resistance up to 240°C (max 260°C)
- Outstanding resistance to acids, alkalis, and organic solvents
- High filtration efficiency for fine dust particles
- Unique trilobal fiber structure increases filtration surface area
- Low pressure drop and stable performance
- Long service life in harsh conditions
