Membrane Technologies Available

Unique-Mem track-etched membranes


Unique-Mem® Unlaminated Track-Etched Membranes

Unique-Mem® track-etched membranes, available as hydrophilic or hydrophobic, are characterized by cylindrical shaped pores penetrating the membrane in different angles. They have a smooth flat surface and well-defined flow rates.

RoTrack Track-etched Membrane


RoTrac® Laminated Track-Etched Membranes

RoTrac® track-etched membranes are Unique-Mem® membranes that are supported with non-wovens (PP or PET) to create a more robust membrane. They are available as either hydrophilic or hydrophobic membranes.

Fiber-Based track-etched membranes


Fiber-Based Membranes

Fiber-based membranes are surface modified using a super-hydrophobic coating to repel water and other liquids while still allowing maximum airflow.
