Protection Vents for Portable Electronics

Porex Virtek IP-Rated Protection Vents and Track-Etched Membrane Technology Provide Maximum Defense

Portable Electronic Vents Tailored to Your Needs

From smartphones to electric toothbrushes, consumers use a multitude of electronic devices on a daily basis. For manufacturers of these devices, protecting the sealed, electronic components is critical to ensuring the device performs as intended and does not pose a safety risk to the end user. To protect these electronics in items like cell phones, digital cameras, headphones, wearables, and more, Porex’s Virtek® IP-rated protection vents and Oxyphen’s track-etched membrane solutions provide protection against contaminant media and can be customized by shape and performance needs.

Portable electronics manufacturers know the importance of keeping their electronics running smoothly. To ensure a positive end-user experience, Porex’s high-performance Virtek® IP rated PTFE protective vents and Oxyphen’s track-etched membrane solutions are designed to reduce pressure buildup while also providing protection against dust, water, sweat, and other contaminants. This can help to avoid potentially dangerous over-pressurization within the device that can lead to premature failure.

Options for Customizing Protection Vents for Portable Electronics

Allows heat to escape electronic enclosures which can prevent premature failures
Repels dust, water, sweat, oils, and other liquids from entering sealed electronic enclosures
Sintered structure allows for ease of handling and welding – no cumbersome assembly instructions and processes that are typical with expanded PTFE
100% PFOA free – compliant with (EC) 1907/2006 REACH / Regulation (EU) 2019/1021 POP
