Product Description
Aramid Needle Punched Felt is a high-temperature filtration material made from aramid fiber and processed through needle punching. It is designed for industrial gas filtration where elevated temperature and chemical resistance are important considerations.
Aramid felt can operate at 204°C continuously and up to 240°C for short-term exposure, with strong alkali resistance and moderate acid resistance. It is particularly suitable for treating hot gases in the 180–220°C range.
Key Features
Strong Alkali Resistance
Industrial flue gases can contain chemically active components that gradually affect filter media. Aramid fiber provides strong resistance to alkaline conditions, making it suitable for selected chemical and industrial filtration applications.
Suitable for Hot Flue Gas
The product is specifically described as suitable for treating 180–220°C hot gases, giving it a practical position in high-temperature dust collection systems.
Built for Continuous Industrial Filtration
The three-dimensional needle-punched structure provides a stable nonwoven filtration layer that can be processed into filter media and industrial filter bags.
Product Applications
Aramid felt is designed for hot gas treatment in the 180–220°C range, making it suitable for selected industrial flue gas filtration systems.
1. Steel & Metallurgy
High-temperature dust and gas filtration is common throughout steel and metallurgical production. Aramid felt can be used in suitable dust collection systems operating within its recommended temperature range.
2. Cement Plants
Cement production generates large quantities of dust, often accompanied by elevated gas temperatures. Aramid filtration media can be considered for appropriate high-temperature dust collection applications.
3. Chemical Processing
Where alkaline or chemically active gas conditions are present, the material's chemical resistance can be an important selection factor.
4. Industrial Flue Gas Treatment
The manufacturer's needle-punched filtration products are used across steel, cement, chemical, power generation, machinery, and other industrial sectors for dust-containing gas purification and material recovery.
