Customized Solutions

Match Our Technologies to Your Requirements

Great discoveries and improvements invariably involve the cooperation of many minds.” – A.G. Bell

As a team of scientists, problem solvers, engineers, and strategic thinkers, Oxyphen is passionate about partnering with our customers to create high-value solutions that bring their product design or concept to life. By leveraging Oxyphen’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.

Highlighted Case Study

Electronic Textiles

Oxmotex AG is a research and development company dedicated to electroosmotic vapor and fluid transport, who developed revolutionary proprietary technology for electronically controlled moisture transport in membranes and textiles. As they looked to create a new innovative technology that would provide active electronically driven moisture transport, they came to Oxyphen for a track-etched membrane solution that would be responsive to changing climates, transport moisture beyond normal sweat rates, and be comfortable for the wearer.
