Delivering Precision & Control: An Introduction to Track-Etched Membrane Technology


Recorded on:
Nov. 12, 2020

11:00 am EST / 8:00am PST

In this webinar, learn about a unique porous polymer technology that is lesser known than the traditional sintered plastics, bonded fiber, and open-cell foam offered by Porex.  Designed and manufactured by our new sister company Oxyphen, track-etched membranes feature a unique pore structure that provides the most precise control over pore size and pore density available in the industry.  The unique two-step manufacturing process can target specific customer requirements for pore size and density that affect air flow and water entry pressure, making these membranes perfect for venting and filtration applications.  Due to their smooth surface, track-etched membranes are an ideal surface filter with reversible and self-cleaning functionality that can be used for hydrophobic, hydrophilic and oleophobic applications.   

Perfect for design and manufacturing engineers who either have a next-generation product concept or need to fix a problem with an existing product, this webinar will illustrate how this technology is used in a variety of applications from cell culture inserts and IV infusion filters to automotive headlight vents and industrial cap vents.  

Join hosts Avi Robbins, head of product development and R&D for Porex, and Stefan Sproll, head of development for Oxyphen, as they take attendees through the science inside track-etched membrane technology and how it can be used to achieve precision in both venting and filtration. 

What you will learn in the webinar:

  • Learn how track-etched membranes are designed and manufactured
  • See the technology in action in specific venting and filtration examples across life sciences, automotive and industrial markets
  • Understand how to use the precise control of the manufacturing process to increase performance of your end product
