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.


10+years of Eptfe membrane production experience






Industry leading level of Eptfe membrane products and customization services



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...

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...

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, ...

High-efficiency ePTFE filter membrane — the reference product for H11, H12, and H13 grade comparison. Source: CY-PTFE high-efficiency ePTFE filter membrane. TL;DR H11, H12, and H13 are EN 1822:2019 HEPA filter grades. H11 reaches >= 95 percent overall efficiency; H12 reaches >= 99.5 p...

A side-by-side performance comparison of ePTFE membrane and nanofiber filter media: filtration efficiency, pressure drop, temperature, chemical resistance, moisture handling, and the right choice for your application. TL;DR — ePTFE vs Nanofiber Filter Media ePTFE is a true microporous membrane ...
