P84 (polyimide) needle felt
P84 polyimide needlefelts 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
• P84 can operate continuously, under practical and low acid working conditions, at temperatures up to (280 °C).
• High filtration efficiency, high tensile strength.
• The complex cross sectional shapes create 30-90% more collection surface area when compared to round or oval shaped fibers.
• Low back washing pressure, maximun flexibility
• The unique tri-lobal fiber structure of P84 provides customers with high efficiency filtration, low pressure drop, and reduced cleaning energy.
• Excellent dust cake release
• P84 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
