FMS Needle-Punched Felt

FMS Needle-Punched Felt Overview

FMS Needle-Punched Felt is a high-temperature composite-fiber filtration material engineered for extremely hot, chemically aggressive, and high-stress industrial flue-gas environments. By combining fiberglass, aramid (or other high-temperature fibers), and optional PTFE-based surface treatments, FMS provides outstanding resistance to heat, acids/alkalis, corrosion, abrasion, and long-term mechanical fatigue. It is designed to perform reliably under heavy dust loads and harsh operating conditions.

Where FMS Performs Best

Blast-furnace gas and metallurgical smelting
Cement kilns and high-temperature clinker/calcining processes
Waste-to-energy incineration systems
Coal-fired and biomass power plant boilers
High-temperature, dust-laden industrial gas streams

Key Selection Criteria

Temperature profile: continuous and peak (240–260 °C continuous, 280–300 °C peaks)
Chemical composition: acid/alkali levels, chlorides, sulfates
Dust characteristics: abrasiveness, hardness, particle size distribution
Filtration load: air-to-cloth ratio, filtration velocity
Cleaning system parameters: pulse-jet intensity, frequency
Baghouse design compatibility and mechanical stress conditions

Key Performance Benefits

Exceptional High-Temperature Resistance

Withstands continuous 240–260 °C operation and 280–300 °C peak temperatures without shrinkage, brittleness, or structural degradation.

Outstanding Chemical Stability

Resistant to acids, alkalis, chlorides, sulfates, and corrosive flue-gas components—ideal for cement kilns, metallurgy, WtE, and high-temperature industrial gas streams.

Enhanced Abrasion & Wear Resistance

Composite fiber structure (fiberglass + aramid) offers superior durability against high-velocity dust, abrasive particles, and mechanical fatigue, extending bag life in harsh systems.

Compatible with Advanced Surface Treatments

Can be upgraded with PTFE impregnation, PTFE membrane, singeing, or calendaring to improve dust release, chemical resistance, and long-term filtration stability.

Engineered for Extreme Industrial Conditions

Perfect for metallurgical smelting, blast-furnace gas, cement clinker lines, waste-to-energy incinerators, and other systems with intense heat, corrosive chemistry, and heavy dust loading.

Flexible Supply & Customization Options

Available as roll goods or as custom-fabricated filter bags tailored to application-specific requirements such as temperature, chemistry, and mechanical stress.
