Protect and enhance sensor performance with cutting-edge technology
Manufacturers around the world trust Porex for cutting-edge technology that outperforms the competition. POREX® materials maximize performance for many sensor applications, including gas absorption, venting, diffusion and electrolyte holding and wicking.
Our customizable solutions for sensor manufacturers can be tailored to specific applications or devices and seamlessly integrated with many manufacturing processes.
Gas Absorption Filters
Filters customized with gas-absorbing material from Porex are designed to target specific gases that may cause a sensor to have a false reading or cause premature degradation of the cell itself.
Expertly and individually designed for your sensor devices, our gas-absorbing filters:

Options for customizing gas sensor absorption filters

Protection Vents and Diffusion Layer
Equalize pressure and repel contaminants
POREX Virtek® IP-rated PTFE vents are designed to provide fast gas diffusion, while repelling dust, water and other contaminants. Specifically designed for electronic devices, our protection vents:

Electrolyte Reservoirs and Wicks
Reservoirs and wicks are needed to retain and deliver an electrochemical system’s electrolyte to facilitate the chemical reaction. POREX® fiber and foam media can be used for reservoirs, general wicking and supporting fluids within electronics and sensors.
Engineered for optimal capacity and directional flow, our electrolyte reservoirs and wicks:
- Minimize inhalation and skin hazards – Made from safe-to-use PP or PE, our materials eliminate the need for glass wool, which can cause skin irritations and health issues when inhaled.
- Meet your application specifications – Product fluid retention, density and flow orientation can be tailored to meet your specific application needs.
