P84 Needle Felt

P84 Needle Felt–Product Introduction

P84 Needle Felt is a high-performance industrial filtration material made from polyimide(P84)fibers,known for its exceptional heat resistance,chemical stability,and mechanical strength.It is widely used in high-temperature dust collection and industrial filtration systems where conventional filter materials cannot perform reliably.

Key Features

Excellent High Temperature Resistance

P84 needle felt can operate continuously at temperatures up to 260°C and tolerate short-term peaks up to 280°C,making it ideal for high-temperature flue gas filtration.

Outstanding Chemical Resistance

Resistant to acids,alkalis,and most organic chemicals,providing durability in harsh industrial environments.

High Filtration Efficiency

Needle-punched fiber structure effectively captures fine dust particles while maintaining good airflow.

Durable and Wear-Resistant

Strong fiber construction ensures long service life in abrasive and demanding dust collection systems.

Smooth Surface for Efficient Cake Release

Reduces dust adhesion and allows easier cleaning during pulse-jet or mechanical dust removal.
