Nomex/Aramid Needle Filter(filter bag)

Description

Nomex( Meta Aramid) Non Woven Needle Felt Filter Cloth

Metamax needle felt(Nomex felt)
Metamax needle felt is meta-aramid fiber invented and manufactured by Heading Filter. NOMEX fibers are from the generic fiber group called meta-aramid. Another brand name from this fiber group is CONEX and NOMEX. .

Features:

  • Chemical Resistance to weak Acids, weak Alkalis and Organic Solvents
    • Thermal stability and low contraction performance;
    • Wearability and the folding endurance make it the perfect product for many kinds of dust structure and the dust quantity.
  • High break elongation ratio guaranteed the end product of filter materials with high intensity, good product longevity, and better tolerance to injection;
    Perfect combination of performance with price – high performance to price ratio
    • It is flame resistant with self-extinguish nature and non-melt drop.

Applications:
• Tail gas/fume/dust from metallurgical plant
• Chemical Resistance to weak Acids, weak Alkalis and Organic Solvents
• Carbon black plant, iron works(blast furnace gas)
• Cement plant (tail gas from vertical kiln),
• Petroleum fumes from mixing round the beton and asphaltum
• Coal fired boiler
