Porex is a leader in custom porous polymer solutions.

Porex manufactures IP-rated porous PTFE membranes to protect sensors from particulates and water, as well as advanced glass-fiber filters with functional additives (e.g. activated carbon) for gas sensors.  Porex porous PTFE and PE membranes are used as catalyst support and diffusion layers within chemical gas sensors.  Porex materials can enhance your sensor technology by providing functionality such as gas-absorbing filters, electrolyte reservoirs, and dust covers. 

Porex is a global leader in developing custom-engineered porous polymer solutions that become high-value functional components in our customers’ products.  Our material solutions leverage a variety of porous plastic technologies, including sintered particles, bonded fiber and open-cell foam.  By combining our material science expertise in absorption, diffusion, filtration, wicking and venting with our global manufacturing capability, we help manufacturers in electronic, healthcare, consumer and industrial industries turn their product ideas into reality.

  • Gas-Absorption Filters
    Minimize false readings or premature degradation

    Gas-absorbing filters from Porex target specific gases that may cause a sensor to have a false reading or cause premature degradation of the cell itself....

  • Specifically designed for your sensor devices, our gas-absorbing filters:

    • Are effective at capturing a wide range of gases that can be harmful to your sensor, including H2S, SO2, HMDS, organics, alcohols and many others.
    • Absorb larger amounts of the problem gas –Compared to competitive materials, POREX® filters absorb more problem gas per unit volume, lasting longer than competitive products.
    • Contain safe materials–POREX filters are constructed with safe-to-use reagents, unlike competitive products with toxic lead-containing components.
