Gore Advances Pressure Venting Technology In Portable Electronic Devices

ELKTON, Md., Nov. 27, 2018 /PRNewswire/ -- People are taking their smartphones and other portable electronics everywhere and through all conditions, subjecting their devices to temperature changes, rapid altitude and pressure shifts, compression of sensitive touchscreens and even immersion in liquids. W. L . Gore & Associates (Gore) has developed the new GORE® Pressure Vents product model PE13 to protect portable devices from water and dust ingress while maintaining optimum pressure in the unit.

GORE® Pressure Vents product model PE13 offers nominal airflow of 19,000 ml/min/cm2 @ 70 mbar (nearly double the airflow of its nearest competitor, Gore's product model PE12), effectively minimizing speaker and receiver distortion caused by transducer bias. The new vents are IP68-rated for water immersion protection up to 1.5 m for 30 minutes.

Available in custom and standard sizes*, new GORE® Pressure Vents product model PE13 gives manufacturers greater design flexibility – to either reduce the number of pressure vents used in their devices, or reduce the size of pressure vents for devices with limited internal space – without reducing effectiveness.

Extreme Pressure Meets Ultimate Protection

Portable electronics are expected to reliably stand up against the elements while processing mor, working faster and going further. As such, the latest devices are being pushed to the very limits as manufacturers pack in an ever-increasing number of new components and sensors, increasing internal pressures.

Over time, these issues can put stress on housing seals allowing water and contaminants to enter devices, creating pressure build-ups in acoustic cavities. This causes transducer bias, compromises acoustic quality, and results in unsatisfied customer experience.

"With product model PE13, our goal was to engineer a pressure vent that effectively minimizes speaker and receiver distortion, while maintaining a high level of particle contamination and water protection," said Anthony Chiu, Product Manager for GORE® Portable Electronic Vents Business Unit.

"When it comes to pressure venting, we always look to maintain a delicate balance between water resistance and air permeability," said Chiu. "Gore's advancement in ePTFE membrane technology has enabled us to achieve extremely high air permeability without comprising dust and water protection."
