Knowledge Base
Polyimide contributes high-temperature performance, while PTFE adds exceptional chemical corrosion resistance. Blending them gives the media both thermal stability and durability in aggressive gas streams.
The heavy-duty PTFE scrim reinforces the media, increasing tensile strength and helping the filter bag maintain dimensional integrity throughout its service life.
The media releases dust cake easily during pulse cleaning, which keeps operational resistance low and reduces the fan energy needed to maintain airflow.

Typical applications include waste incineration, coal-fired boilers, steel manufacturing, cement plants, and chemical processing where high temperature and corrosive flue gas occur together.
Engineered for hot, corrosive baghouse duty.
