Oleophobic Membranes
Unmatched Performance Against Both High and Low Surface Tension Fluids Like Oil
Gore oleophobic technology has been successfully proven in a wide range of venting applications through years of commercial field experience. These “oil-fearing” materials resist wet-out from low surface tension fluids. It is more difficult for the fluids to penetrate oleophobic membranes from Gore, leading to high performance in a number of demanding applications.
Common Fluids @ 22°C (dynes/cm)
| Mercury | 484 |
|---|---|
| Water | 73 |
| Glass Cleaner | 38 |
| Oil | 30 |
| Benzene | 29 |
| Detergent Wash Solutiona | 27 |
| Isopropyl Alcohol | 22 |
| Unleaded Gasoline | 19 |
Ideal applications for oleophobic membrane vents include:
- Electronic enclosures
- Electronic control units
- Various sensor applications
- Exterior lighting
- Any components exposed to chemical agents
Oleophobic membranes have performed well when exposed to a wide variety of high and low surface tension fluids, dirt and other typical aqueous solutions.
