Industrial Filtration Media | PTFE/PI NEEDLEFETL
Detailed

PTFE/PI NEEDLEFETL  630 g/m2 (18.5 oz/yd2)

 

Description

Blended For Versatility in Aggressive Environments

High Durability Filter Bags blend chemically inert expanded polytetrafluoroethylene (ePTFE) with rugged polyimide fibers.

This hybrid offers significant performance increases over aramid felts both in mechanical endurance and chemical resistance. It provides product recovery and emissions control unequalled by nonmembrane filters.

 

The polyimide/ePTFE blend provides better humidity and chemical protection compared to aramid and polyphenylensulfide (PPS) felts. Additionally, its temperature range goes all the way to 260 °C

(500 °F). This capability means much better protection against process upsets due to temperature fluctuations. An additional benefit of the blend is its higher resistance to acids compared to aramid fibers. The enhanced performance of the polyimide/PTFEbacker is very effective for applications requiring more chemical and thermal endurance than traditional felts made with aramid or PPS fibers.
