Polyamide (PI/P84) Needle Felts
1.Brief Introduction Of P84 Filter Media
P84 (PI-polyimide) is a filter material with the properties of flame resistance, high temperature resistance.
Polyimide will keep a good performance when the temperatures up to 240 degree centigrade, instant can
up to 260 degree to 300 degree. Polyimide is leaf-shaped structure with a larger filter surface, and always
embedded in the surface of other needle felt with different material to improve the filter efficiency. For the
properties of high Temperature resistant filter material, good chemical resistance, good air permeability,
high filtration efficiency, mostly applied in Cement kiln, Asphalt, Waster Incinerator, coal boilers, etc.
2.We pay attention to following processing matters:
(1) Precise design required size of the filter cloth for filter bag parts, the filter cloth will larger than the actual amount design size, to leave a spare for weaving.
(2) To choose the right filter bag accessories, specifications and check its quality. The filter bag accessories should match the filter bag quality requirements.
(3) We make the filter bag line drawing, cutting, sewing on automatic production line. When the filter bag need manual processing, we will open it on the operation platform, and with certain pulling force to keep it is flat.
(4) We keep the strict processing quality standards, according to design drawings and operation process. Our worker meet the requirements of tooling and clothing , no smoking.
(5) We have the responsible for the processing of products, and examines, waste, residue, defective goods in the beginning.

The filter bag 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.
