Description
P84 fiber is a special-shaped (trilobal) cross-section structure, which has a large filtration surface area and excellent filtration performance. Therefore, P84 fiber is often implanted into the surface layer of filter material (dust facing side to improve the filtration performance of filter material)
Maximum Continuous in Dry Conditions: 245°C / 473°F
Maximum Surge in Dry Conditions: 255°C / 491°F
Product features
Remarkable temperature resistance
Good chemical resistance
Low backwash pressure and high cake removal efficiency
Typical applications
P84 is mainly used for flue gas purification in asphalt mixing, cement kiln, drying, combustion, smelting, various industrial kilns, coal-fired boilers and waste incineration, and is widely used in processes with high emission concentration requirements
