Nonwoven needle felt / Nonwoven filter cloth / Needle felt for filter bag / Composite material needle felt

Low-Medium Temperature Needle Felt

●Material:PE,PP,Acrylic

●Working temperature:less than 160℃

●Advantage:good air permeability,high porosity,smooth surface,good acid&alkali resistance,good chemical properties,high dust collection efficiency,easy dust removal and high durability etc.

●Technical used:needle punching&other finish treatment.

●Application:steel industry for iron smelting,casting and electric furnace dust collection,dealing with the exhaust in electrolytic aluminum fume,alumina transmission and non-ferrous smelting industries;Ordinary dust removal and normal-temperature exhaust treatment etc.

High temperature corrosion resistance needle is a kind of high efficient filtration material,which made by high temperature and corrosion resistance staple fiber,and finish with special treatment.

It have advantage of good flexing resistance,good corrosion resistance,good abrasion resistance,exnt dust collection efficiency and high ash removal efficiency.

It’s widely applicate for working condition with high temperature gas,such as chemical industry,non-ferrous metal smelting,coal-fired boiler,waste incineration and cement kiln etc.

PPS(Polynylene Sulfide) Needle Felt Features

●Exceptional stability for a wide range of temperature and frequency variations.

●Be suitable for the oxygen content below 15%.

●Chemical resistance to acid,alkali and organic solvents,contain moisture in the flue gas.

●Very stable with stability standard at 2% shrink or stretch,limited oxygen index 34-35.

Aramid composite needle felt is made by Aramid staple fiber,and finish with special treatment.

It have advantage of high temperature resistance,good abrasion resistance and exnt chemical stability.It have better tensile strength than Fiberglass felt,and price of Aramid fiber is much lower than US Dupont Nomex fiber,but can performs same as Nomex felt in high temperature working condition,so it widely applicate for chemical industry,metal smelting,aslt mixing plant,waste incineration,cement kiln and coal-fired boiler etc with perfect peformance and long service life.

Fiberglass composite needle felt is special filter material which produce base on 5.5μm fiberglass fiber,and mixed with other high temperature staple fiber such as P84,Aramid,Kevlar,PPS and PTFE with special finish treatment.It have special three-dimensional microporous structure with low running resistance.Especially mixed with P84 staple fiber,due to P84 staple fiber special leafy structure,the fiber superficial area can increase about 80%,so it have strong ability of dust collection.Because of complementarity of Fiberglass fiber and P84 staple fiber,so the Fiberglass composite filter material can catch tiny dust and have exnt abrasion resistance,which also increase the peel strength and filtration velocity,it can reach 1-1.4m/min,strongly increase the filter bag’s service life.

It’s widely applicate for metallurgical industry,non-ferrous metal industry,chemical industry,cement kiln and coal-fired boiler with good performance and competitive price.Â

PTFE Needle Felt Features

●Be composed of 100% pure PTFE staple fiber and scirm.

●Can operate under 240℃ continuously.

●Good acid and alkali resistance,good corrosion resistance,and strong chemical stability(0-14 .Â

●Can be used under high humidity working condition.

●Low shrinkage rate even if under high temperature working condition.

●Aging resistance and no environment pollution.

It’s mainly applicate for working conditions with high temperature gas,such as chemical industry,coal boiler,waste incineration and non-ferrous metal smelting with good performance and long service life.
