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
