500 – 650g/M2 P84 Dust Filtration Bag Needle Felt Filter Bag Wear Resistance
Dust Filtration Needle Punched Felt Polyamide Singeing P84 Filter Bag
P84 Filter Bag Introduction:
P84 filter bag is a kind of flame-retardant, temperature-resistant and stable fiber filter material. Under the condition of 240℃, the mechanical properties of P84 polyimide fiber filter material will not change, and the maximum temperature resistance can reach 260℃. P84 fiber filter material has no melting temperature and is naturally golden yellow. P84 polyimide fiber filter material is not a hygroscopic fiber filter material (about 3% water absorption at 65% relative humidity).
In addition, since the P84 fiber is a special-shaped (leaf-shaped) section structure, it has a large filtering surface area and excellent filtering performance, so the P84 fiber is often implanted in the surface layer of the filter material (the dust-facing side to improve the filtering performance of the filter material). ).
P84 Filter Bag Advantage:
Excellent stability in applications with high dry heat temperatures, mineral acids and alkaline.
P84 Filter Bag Disdvantage:
Must oversize bag for shrinkage that can occur in temperatures above 450 Degrees F.
