Product Name: P84 (polyimide) needle felt 
Specification: 
  

   P84 polyimide needlefelts are excellent high temperature filter media in terms of performance, generally surpassing the other standard media with the exception of PTFE.

   P84 Fiber 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 ).

· High filtration efficiency, high tensile strengh

· 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.
