PTFE Membrane Laminated Composite Filter Bag Manufacturer

PTFE Membrane Laminated Composite Filter Bag

: http://jdx-filtration.com/1-1-2-ptfe-membrane-filter-cartridge.html

The PTFE membrane laminated composite filter bag utilizes PTFE as the main material, and processes it into a single micro-porous membrane, then coats the membrane in various fabrics or other base materials. The PTFE composite filter bag is an ideal filtration choice for its chemical stability, smooth surface, low friction coefficient, temperature resistance, aging resistance, durability, air permeability and waterproof coating.
