Hydrophobic and Oleophobic PP Membranes

Download Image

Our hydrophobic and oleophobic PP membrane is produced by laminating PP filter media, followed by surface modification to achieve a hydrophobic and oleophobic surface, which helps to resist water and low-surface tension liquids with excellent air flux.

Specially selected polymer is clean and safe
Unique bonding technology enables easy fabrication
Depth filtration media provides porosity, high throughput, high capacity
Oleophobic/hydrophobic treatment repels various fluids, preventing permeation
Available in various shapes and customized sizes to meet your unique application needs
