Aramid Needle Punched Felt

Aramid needle punched felt  possesses many excellent properties of aramid fibers, such as high strength, high temperature resistance, flame retardancy, and chemical corrosion resistance. It is commonly used in fields like industrial filtration and as the filling material for individual protective clothing.

High-Temperature Resistance

Key Features

● Can be used continuously at 200°C and withstand even higher temperatures (e.g., above 250°C) for short periods.

● Maintains stable physical and chemical properties in high-temperature environments.

Flame Retardancy

● Aramid fibers are inherently self-extinguishing and will not continue to burn after the flame source is removed.

● Meets flame-retardant material standards, making it suitable for high-temperature and flammable environments.

Chemical Corrosion Resistance

● Exhibits excellent resistance to most acids, alkalis, and organic solvents.

● Suitable for corrosive environments such as chemical and metallurgical industries.

Mechanical Properties

● High strength and wear resistance, ensuring a long service life.

● The needle-punching process creates a tightly interlocked fiber structure, providing stability.

Filtration Performance

● Uniform fiber fineness and well-distributed pores result in high filtration efficiency.

● Ideal for filtering high-temperature gases and dust.

● Used for high-temperature gas filtration in industries such as steel, cement, and power generation.

● Serves as filter bag material in baghouse dust collectors, offering high filtration efficiency and long service life.

Application field

Aramid needle punched felt is an ideal choice for the following high-temperature flue gas dust removal scenarios:

·Asphalt mixing plant: Perfectly responding to the high temperature and high oil dust of asphalt smoke, it is the standard filter material in this industry.

·Carbon black production and transportation: extremely strong wear resistance and heat resistance, used for collecting carbon black dust.

·Metallurgical industry: high-temperature smoke and dust treatment for electric furnace steelmaking, ferroalloy smelting, aluminum plants, etc.

·Cement industry: filtration of flue gas in high-temperature areas such as kiln head and kiln tail.

·Chemical industry: Dust recovery during processes such as drying towers and calcination furnaces.

·Coal fired boiler: used for pulse jet dust collector to treat high-temperature flue gas.
