Protection Vents for Portable Electronics

Porex Virtek® IP-rated protection vents

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 can supply sintered Virtek® IP-rated protection vents to provide a tougher, more durable solution that can withstand handling, ultrasonic welding, and heat bonding without additional support material. In addition, these venting solutions can be customized by shape and performance needs – available as adhesive discs, sheets, rolls, and custom forms and shapes.

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 are designed to reduce pressure buildup while also providing protection against dust, water, sweat, and other contaminants.
