Automotive – Lighting & Electronic venting
Lighting Vents
Enhanced Safety with Porex Virtek PTFE and Oxyphen Automotive Headlight Vents
Equalize Pressure While Minimizing Humidity Flow Using Lighting Vents
From getting people to work to transporting goods, automobiles play a vital role in our daily lives and the global economy. Whether you’re driving in the early morning or late at night, having reliable and effective automotive lighting is essential for the safety of your vehicle’s occupants and other road users.
Porex understands the critical importance of automotive lighting and offers innovative solutions for lighting vents. Our specialized venting materials are designed to provide fast de-condensation and protect automotive lighting systems from moisture, dust, and other environmental contaminants that can compromise their performance. By integrating Porex’s high-quality venting solutions, automotive manufacturers can ensure that their lighting systems remain clear, functional, and reliable, even in demanding conditions.
Automotive Lights
Without the fragility and variability common in non-sintered materials, POREX Virtek® PTFE, which is specifically designed for exterior automotive lights, uses unique sintered material that outperforms competitive expanded materials. With its robust porous structure, our vents equalize pressure while minimizing humidity flow into the enclosure, protecting enclosure seals from premature failure.

Oxyphen Automotive Large Lamps
More efficient ventilation and protection are increasingly demanded for automotive lighting applications. Clear glass systems used in headlights need not only adequate airflow to cool the system but must also prevent condensation of moisture and protect against the ingress of liquid, dirt, and other contaminants that can lead to malfunctioning and reduced illumination.
Oxyphen’s expertise in the automotive market led to the development of specific hydrophobic, high-gas flow track-etched membrane solutions with unmatched vapor transmission rates that provide fast de-condensation and protection of headlights, rear lights, and other large automotive lamps.

Oxyphen Automotive Small Lamps
For side indicators, fog lamps, or other lightning devices where the mounting spot is on the vehicle’s exterior and directly exposed to the harshest weather condition, fogging and cracks can occur. To function properly, these lighting systems must have proper airflow for cooling, prevent the ingress of contaminants such as liquid and dirt particles, as well as prevent condensation of moisture which can all lead to malfunctioning of the part.
Oxyphen’s hydrophobic track-etched membrane solutions with unmatched vapor transmission rates offer an ideal solution for small lamps used in automotive applications through their ability to remove moisture, protect against contamination, and cool the module through a pre-determined airflow.
