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 Solution 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.
