P84 needle felt

P84 is a high temperature resistant Synthetic fiber. P84 fiber is made of a condensed polymer, and high-temperature filter bags are not resistant to hydrolysis. P84 needle punched filter felt has the characteristics of high temperature resistance (260~280 ℃), good chemical resistance, low backwashing pressure, high rebound and cake removal efficiency, good air permeability, and high filtration efficiency, but its price is relatively high. It is mainly used in asphalt mixing, cement kiln, Incineration furnace, fluidized bed boiler and coal-fired industrial furnace.
