A PTFE Membrane Fiberglass Filter Bag is a high-performance industrial filter bag made by laminating a PTFE (polytetrafluoroethylene) microporous membrane onto a fiberglass substrate. This combination provides exceptional filtration efficiency, chemical resistance, and dust release, making it ideal for high-temperature and corrosive gas environments.

🔹 PTFE Membrane Fiberglass Filter Bag – Overview ✅ Construction:
Base Fabric: Woven or felted fiberglass—withstands high temperatures and aggressive gas streams.
Surface Layer: PTFE membrane (expanded or laminated) — a microporous, non-stick layer that traps sub-micron particles on the surface, allowing for surface filtration instead of depth filtration.
