Baghouse Filtration: ePTFE Laminate Specifications for Dust Collection
An ePTFE laminate is a membrane thin enough to be measured in micrometres, bonded to a felt thick enough to hold a bag’s shape. The datasheet is short, and most arguments about performance come down to how three of its lines are read. Ningbo ChaoYue technical team, cy-ptfe.com·Published 20...
Oleophobic ePTFE Vents: When Do You Need Oil Resistance?
An oleophobic vent membrane is not a default upgrade over a plain hydrophobic one. It earns its cost only when a sealed enclosure will actually see oil, fuel, grease or surfactant. If the enclosure will only ever meet rain and condensation, a hydrophobic-only membrane vents just as well for les...
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...
