Nomex (Aramind) needle felt is a high-performance synthetic fiber and one of the most widely used dust removal materials. Our company adopts fibers produced by DuPont in the United States, which have excellent properties such as ultra-high strength, high modulus, heat resistance, acid and alkali resistance, and lightweight, and heat-resistant flame retardancy, among others, making them suitable for various applications.

Compared to ordinary fiber filter felts, aramid has the following advantages:
Meager shrinkage rate in high-temperature environments, maintaining a 1% shrinkage rate even after 1000 hours of use at 250°C.
Fire resistance: It begins to decompose at 400°C, with a limiting oxygen index (LOI) of 30, and does not contribute to combustion even in self-ignition conditions.
It can work continuously below 200°C, with an instantaneous temperature of 250 degrees Celsius.
Excellent resistance to acid and alkali corrosion.
