Polyimide(P84) Dust Collector Filter Bag

1.the feature of P84 needle punched felts bags in Thailand

P84 polyimide needle felts are excellent high temperature filter media in terms of performance, generally surpassing the other standard media with the exception of PTFE.
P84 fiber filter material has no melting point temperature and is naturally golden yellow. the P84 polyimide fiber filter material is not a hygroscopic fiber filter (about 3% water absorption at 65% relative humidity). 
in addition, since the P84 fiber is a profiled (leaf-type) cross-section structure with a large filtration surface area and excellent filtration performance, P84 fiber is often implanted on the surface of the filter material to improve the filtration performance of the filter material.

5. Application field:

P84 is mainly used in flue gas purification of asphalt mixing, cement kiln, drying, burning, smelting, various industrial kiln, coal-fired boiler and waste incineration, and is widely used in processes with high emission concentration requirements.

6. ThE Water-Oil repellent Non-woven needle felt P84/Polyimide dust filter bag with PTFE membrane for air filter collector Packaging:

Different types of filter bag must be individually packaged. In general, it is wrapped in plastic bags for water proof, then put in a carton. Filter bag must be neat and regular packing, with the ring of the filter bag to avoid ring flat compression deformation. For the requirement to keep the shape of filter bag, it must fill padding for filter bag inside. Any other packing ways also be accepted up to you.
