High-Temperature Meta-Aramid Filter Bags – Nomex® Filter Bag Equivalent
Our high-temperature meta-aramid filter bags are engineered for industrial dust collection under extreme heat conditions. These bags offer excellent thermal stability, abrasion resistance, and long service life. They are equivalent in performance to Nomex® filter bags.
As an experienced filter bag manufacturer, we provide custom solutions for various industries, including asphalt plants, cement kilns, steel mills, and foundries.
Properties of Nomex Filter Bags
- Heat Resistance：Nomex filter bags can withstand continuous operating temperatures up to 204°C and short-term peaks up to 240°C
- Chemical Resistance：They offer good resistance to acids and alkalis, making them suitable for use in environments with harsh chemicals.
- Mechanical Strength：Nomex fibers provide excellent mechanical strength, ensuring durability and a longer service life.
- Abrasion Resistance：The inherent abrasion resistance of Nomex fibers helps the bags withstand the rigors of dust collection processes.

Tailored Finishing Treatments
01
Singeing / Calendering
Removes loose surface fibers and runs the material through hot calendering rolls for a smooth surface that ensures exceptional dust-cake release.
02
Water & Oil Repellent
Impregnated with Teflon agents to repel moisture and light hydrocarbons, preventing bag-blinding due to local dew-point cooling.
03
PTFE Membrane Coating
Laminates a micro-porous expanded PTFE membrane on the bag surface, enabling surface filtration and capturing particulates down to 0.1μm.
04
PTFE Emprenye
Coats each fiber evenly with a Teflon bath to significantly increase anti-oxidant thresholds and provide friction-free sliding wear properties.
Uygulama
high heat and sticky dust that can clog filters
high-temperature metal dust and sparks
acidic flue gas and variable dust load
abrasive dust causing rapid wear
