P84 polyimide needlefelt filter cloth is a top-notch filter material that excels in high temperature conditions, outperforming most other standard media except for PTFE.
Features:
• Exceptional stability and acid resistance at high temperatures.
• P84 can endure continuous operation at temperatures up to 500°F (260 °C) in practical, low acid environments.
• Offers high filtration efficiency and tensile strength.
• The unique shape of the P84 fibers provides 30-90% more surface area for collection compared to round or oval fibers.
• Requires low pressure for backwashing and offers maximum flexibility.
• The tri-lobal fiber structure of P84 enables high efficiency filtration, reduced pressure drop, and less cleaning energy.
• Boasts excellent dust cake release properties due to its irregular, tri-lobal fibers.
Applications:
• Ideal for use in incinerator plants.
• Suitable for filtering cement kiln gas.
• Effective in low acid coal fired boilers.
• Suitable for capturing flue gas in asphalt/hot mix plants.
• Useful in minerals processing.
• Applicable in soil remediation facilities.
