Aramid İğne Keçe

High-Temperature Dust Filter Cloth

Aramid needle felt (often referred to by the brand name Nomex® needle felt) is a non-woven dust filter cloth made from 100% aramid fibers. Known for its excellent heat resistance, abrasion resistance, and dimensional stability, aramid filter fabric performs reliably under continuous operating temperatures up to 200°C (392°F).

  • Yüksek sıcaklık dayanımı: Nomex needle-punched felt can be used in various dust collectors within 204℃, can work continuously at a temperature of 204℃, and the instantaneous working temperature can reach 240℃.
  • Boyutsal kararlılık: 230°C gibi yüksek bir sıcaklıkta, aramid iğneyle delinmiş keçenin genleşme oranı sadece 1%'dir.
  • Yangın geciktirici: It starts to decompose and carbonize at 400℃, and the limiting oxygen index (LOI) is 36. It does not spontaneously ignite or support combustion.
  • Kimyasal korozyon direnci: Asitler ve alkaliler gibi kimyasallarla reaksiyona girmesi kolay değildir.
  • Aşınma direnci: Nomex iğne delikli keçe ayrıca iyi aşınma direncine sahiptir ve çeşitli yüksek verimli ve yüksek yoğunluklu filtreleme işlerine uyum sağlayabilir.
  • Ayrıca, nomex iğne delikli keçe, iyi hava geçirgenliği, yüksek toz toplama verimliliği, büyük toz tutma kapasitesi ve uzun hizmet ömrü avantajlarına da sahiptir.

Teknik SSS

What is the difference between Aramid and Nomex® filter bags?

A: Nomex® is a registered trademark of DuPont for their meta-aramid fibers. “Aramid” is the generic industrial name for the exact same material. Our filter cloth uses premium meta-aramid fibers, offering identical thermal and chemical performance to branded Nomex, but at a much more cost-effective factory price.

Can you supply finished filter bags or just fabric rolls?

We supply both. We can export aramid needle felt fabric in rolls for local manufacturers, or we can sew ready-to-use filter bags precisely matched to your baghouse dimensions (e.g., snap ring top, raw edge, envelope shape).

How does moisture affect Aramid?

A: Aramid is sensitive to hydrolysis (chemical breakdown caused by high heat and moisture). If your flue gas has high moisture content, we strongly recommend our PTFE impregnation treatment (Water & Oil Repellent) to protect the fibers.
