P84 dust 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 media is not a hygroscopic fiber filter media (at 65% relative humidity, about 3% water absorption).

Since P84 fiber is a special-shaped (leaf-shaped) section structure, it has a large filtration surface area and excellent filtration performance, so P84 fiber is often implanted in the surface layer of other dust bags (the dust-facing side to improve the filtration performance of the filter material) .

P84 high temperature resistant dust bag needle-punched filter felt is made of INSPEC FIBERS polyimide fiber produced by Austrian LENZING company. The dust only stays on the surface of the filter felt and fails to penetrate into the P84 high temperature resistant dust bag filter felt, so the backwash pressure is small and the filter cake ejection efficiency is significantly improved, with excellent fine powder collection efficiency and small operating pressure difference . Suitable for coal-fired boilers, liquid bed boilers, waste incineration, asphalt plants, cement plants, waste gas incinerators, etc.
