P84® (Polyimide) Felt

Polyimide felt (P84®) combines uniquely high abrasion resistance at elevated temperatures (240 deg C).
Multilobal P84® fibres create a low-velocity flow profile thereby increasing filtration efficiency and reducing pressure drop.
P84® provides better bag life in applications where Fiberglass is providing poor life due to abrasion-related failures. Fiberglass is highly fragile and over pulsing, excessive cleaning cycles, and high dust loads can lead to abrasion and membrane failures.
Maxtech is tied up with Testori (Italy) to provide 100% Evonik p84® Fibers.
