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, ...
H11 vs H12 vs H13: ePTFE Filter Grades Explained
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...
