How Long Does an ePTFE Compost Cover Last? Service Life Guide
A compost cover does not wear out in one way, so it does not have one service life. The PTFE in the membrane is effectively permanent, and what ends a cover’s useful life is the composite around it, the ultraviolet it absorbs, the handling it takes and the way it is anchored. A cover life quoted ...
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...
