P84 membrane filter material is a high-efficiency filter material made by coating a layer of PTFE and PU on the basis of P84 filter material.
The mechanical properties of the P84 filter did not change at a temperature of 240 °C. The natural color of P84 filter material is golden yellow.
P84 filter material is not a hygroscopic fibrous filter material (approximately 3% water absorption at 65% relative humidity). In addition, since the P84 fiber is a profiled cross-section structure with a large filtration surface area and excellent filtration performance, P84 fiber is often implanted on the surface of the filter material to improve the filtration performance of the filter material.
