With the upgrading and iteration of consumer electronic products, the requirements for hydrophobic and dustproof levels are constantly increasing, and the pursuit of sound is maintained after passing through the expanded polytetrafluoroethylene membrane Very good signal-to-noise ratio and very low distortion. In 2016, Apple iPhone 7 mobile phone began to raise the hydrophobic and dustproof performance to IP67 level, and the hydrophobic performance of its smart watch Apple Watch Seris2 was further improved to IP68 level. Since then, many mobile phones and smart wearable devices have followed suit and upgraded their hydrophobic and dustproof levels to IP67 and IP68.
Expanded polytetrafluoroethylene membrane has hydrophobic, breathable, and sound-permeable properties. The water pressure-resistant sound-transmitting membrane products developed with these characteristics are beginning to be used in consumer electronics industries such as smart wearable devices and smartphones to seal gaps and holes in the devices, thereby achieving IP67 and IP68 hydrophobic and dustproof levels. The principle is that when sound waves contact one side of the ePTFE film, the film will vibrate, converting the energy carried by the sound waves into physical vibrations. The physical vibrations on the other side of the film will cause the air to vibrate, generating sound waves of similar frequency, thus Achieve high-level sound transmission effects.
The company has standard sizes and can also customize them according to requirements. The products have various installation forms and can provide adhesive patches. Currently in consumer electronics, automobile manufacturing, outdoor lighting, telecommunications equipment and other fields. All are incorporated into our hydrophobic and breathable products. The colors are black and white respectively. Expanded polytetrafluoroethylene membrane technology has always been the core of the business and plays a very important role in many fields such as biopharmaceuticals, equipment, food and beverages, semiconductor manufacturing processes, and communications. 0.1μm to 1μm, providing functional solutions such as fine filtration, hydrophobic breathability, and sound transmission.
