IPRO presents a dustproof ultra-large airflow vent for next-generation mobile devices

For precision devices such as cameras, MEMS microphones, and micro speakers, dust prevention is one of the most significant pain points in product production and user use. Due to its unique three-dimensional microporous structure, the ePTFE membrane has a dustproof effect far superior to mesh, so it is widely used in consumer electronics.

The Benefits of an ePTFE Dustproof Membrane

The ePTFE membrane is a microporous membrane with a three-dimensional structure formed by stretching PTFE powder laterally and longitudinally by a unique process. Among them, the pore diameter of micropores is 0.01-10 μm, the number of micropores is 100000000+/cm2, and the porosity generally exceeds 90%.

In addition, the ePTFE membrane also has a low surface energy (~21 dynes), which is much lower than that of pure water (~72 dynes). Moreover, it has good temperature resistance from -150 ° C to 260 ° C and is resistant to acid and alkali corrosion. Because the ePTFE membrane has a unique three-dimensional microporous structure and excellent chemical stability, it is widely used in waterproof, dustproof, breathable, and sound-permeable fields.

Although the dustproof efficiency of the ePTFE membrane is far better than that of mesh, the air permeability is generally small, which is also a limitation of the application of the ePTFE membrane in the field of dustproof and breathable air.

To solve this problem, after years of research and development, IPRO has successfully developed a dustproof and ventilating membrane with an air permeability of 150,000ml/min/cm2@7kPa and a dustproof rating of IP6X, which can not only meet the highest dustproof level of mobile devices but also It can meet the demanding airflow requirements of various applications.

This is not only in MEMS microphones, micro-speakers, and other devices but also in consumer electronics, automobiles, outdoor electronic equipment, and other industries that require high dustproof levels with ample airflow.
