Aramid Fiber for High-Temperature Filter Media
Aramid fiber offers outstanding heat resistance, mechanical strength, and durability, making it a preferred material for needle felt filter bags in steel, cement, and asphalt industries.
Description
Aramid fiber (commonly known by trade names like Nomex®) is a meta-aramid synthetic fiber valued for its exceptional thermal stability and mechanical strength. It maintains structural integrity under continuous high temperatures up to 200℃, with short-term peaks up to 220℃.
Compared with polyester or PPS fibers, aramid provides higher tensile strength and better abrasion resistance, ensuring long-lasting performance in steel, cement, glass, and asphalt plants where dust, heat, and mechanical wear are severe.
When combined with specialized surface treatments (e.g., PTFE membrane or carbon impregnation), aramid needle felt delivers anti-static, hydrophobic, and flame-retardant properties, extending service life and improving filtration efficiency.
