Customized Solutions

Match Our Technologies to Your Requirements

As a team of scientists, problem solvers, engineers, and strategic thinkers, Porex is passionate about partnering with our customers to create high-value solutions that bring their product design or concept to life. By leveraging Porex’s decades of experience and expertise, our partners can gain a competitive advantage by advancing innovation in markets such as automotive, electronics, industrial, and life sciences.

Through our membrane development, design, and quality manufacturing expertise, we combine different track-etched membrane technologies with plastic molds or adhesives to create turnkey solutions. In addition to customizing our laminated and unlaminated membranes with various hydrophilic, hydrophobic, or oleophobic treatments to increase water flow, wetting abilities, and water entry pressure of the membrane, we can easily adapt pore density, pore size, thickness, and shapes to your specific application.

We want to hear more about your ideas, next-generation developments, and what venting or filtration challenges may be hindering your progress. Let us partner with you to help you get where you want to be.

Membrane Technologies Available

Technologies

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.​.

Technologies

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.

Technologies

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.
