500g P84 Needled Felt P84 High Efficient Punched Filter Cloths P84 High Temperature Filter Felt
P84 is fiber made by Degussa Inspec Fibres, and is a high temperature polyimide fibre. P84 can withstand up to 260℃ in dry heat conditions or 195 where high moisture is present. Unlike most other fibres, P84 has a trilobal cross section which makes its particle capture and filtration efficiency very high. In some industries P84 is used in the filtration surface of other filter media to improve the filtration efficiency. In the cement industry, P84 is the most commonly used fibre where the off gases from the kiln or clinker cooler are high.
According to the different requirements of the different working conditions, we could do various functional processing on P84 fiber high-temperature resistance needled felt, such as water and oil repellent, PTFE impregnation, coating, lamination and so on.

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 500°F(260 °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
