The features of P84 Polyimide Needle Felt:
1.Excellent steady under high temperature and resistance to acid
2.P84 can operate continuously, under practical and low acid working conditions, at temperatures up to 500°F(260 °C).
3.High filtration efficiency, high tensile strength.
4.The complex cross sectional shapes create 30-90% more collection surface area when compared to round or oval shaped fibers.
5.Low back washing pressure, maximun flexibility
6.The unique tri-lobal fiber structure of P84 provides customers with high efficiency filtration, low pressure drop, and reduced
cleaning energy.
7.Excellent dust cake release
8.P84 has irregular, tri-lobal fibers that provide better collection efficiencies and enhanced dust cake release properties.

P84 Tenperature Needle Felt
P84 needle felt has three main advantages
1. High temperature resistance The working temperature is 260, and it has great ability to deal with accidences.
2. Excellent chemical resistance Decades of years of incineration house practice has proved the value of P84 bags, especially for acid gas and alkali dust filtration and collection.
3. Low converse washing pressure and great dust cleaning ability P84 fiber is small dtex, which enlarges the advantage. The erose fiber cross section ensures the largest fiber surface area and provides large number of small openings. Because of this, the dust will be mainly retained on the surface of felt, so the felt will be easily cleaned up. The pressure drop will be very small. P84 felt has been successfully used in asphalt factories, cement factories, incineration factories, and coal burning boilers, etc.
