about
CNbeyond
The main business of our company are PTFE filter membrane, PTFE textile membrane and other PTFE composite material . The PTFE membrane are widely applied in the fabric for outdoor and functional garments, and also used in atmosphere dust elimination and air filtration, liquid filtration. They also have excellent performance in electronic, medical, food, biology engineering, and other industries. Along with the development of both technology and application, PTFE membrane will have favorable prospects in waste water treatment, water purification and sea water desalination, etc.

news and information
Membrane Vent vs Mechanical Vent: Which Should You Choose?
TL;DR A membrane vent and a mechanical vent solve the same problem, pressure equalisation without letting water in, but they fail in opposite ways: a membrane fouls or gets covered, a mechanical vent loses pressure margin or gets clogged with debris. Our ePTFE vent membranes equalise internal ...
IP67 vs IP68: What Vent Membrane Rating Do You Need?
TL;DR IP67 and IP68 are two different tests, not a lower and a higher version of the same test. IPX7 is immersion up to 1 m for 30 minutes; IPX8 is continuous immersion under conditions agreed between the manufacturer and the customer. An “IP68” on a drawing is incomplete until those conditio...
ePTFE Membrane vs Traditional Filter Media in Air Filtration
Hero image: CY-PTFE high-efficiency ePTFE air filter membrane — the expanded PTFE microporous membrane whose fixed pore structure filters by mechanical sieving rather than depth loading. Sourced from the CY-PTFE high-efficiency ePTFE filter membrane. Quick read “ePTFE versus tradition...
ePTFE vs TPU Membrane for Waterproof Garments
TL;DR They are not the same kind of material. ePTFE is expanded polytetrafluoroethylene stretched into a microporous network. TPU is a monolithic hydrophilic polymer film. Most comparison errors come from treating them as interchangeable grades of one thing. The published ePTFE mechanism: aro...
Hydrophobic vs Oleophobic ePTFE: Which Vent Membrane Do You Need?
TL;DR Pick hydrophobic-only ePTFE when the sealed enclosure sees only water (rain, condensation, splash) and you need maximum airflow at the lowest pressure drop — typical ratings: 4000-5000 ml/min/cm² at 70 mbar. Pick oleophobic ePTFE when the enclosure will contact oils, fuels, surfactants, ...
