P84 (polyimide) Needle Felt High Strength

详情

P*4 (polyimide) Needle Felt High Strength
P*4 polyimide needle felt are excellent high temperature filter media in terms of performance, generally surpassing the other standard media with the exception of PTFE.
 
Features
Excellent steady under high temperature and resistance to acid 
P*4 can operate continuously, under practical and low acid working conditions, at temperatures up to **0°F (**0 °C). 
High filtration efficiency, high tensile strength. 
The complex cross sectional shapes create ****0% more collection surface area when compared to round or oval shaped fibers. 
Low back washing pressure, maximum flexibility 
The unique tri-lobal fiber structure of P*4 provides customers with high efficiency filtration, low pressure drop, and reduced cleaning energy. 
Excellent dust cake release 
P*4 has irregular, tri-lobal fibers that provide better collection efficiencies and enhanced dust cake release properties.
 
Applications
Incinerator plants 
Cement Kiln gas 
Low acid coal fired boilers 
Asphalt/hot mix plants flue gas 
Minerals processing 
Soil remediation facilities
