This carefully designed membrane integrates a strong mesh structure support and the extraordinary properties of PTFE, which proves to be versatile and essential for the manufacture of portable and wearable electronic devices. Ultra-low transmission loss means very low signal attenuation and enhanced acoustic integrity for applications such as smart devices, headphones, smart watches and Bluetooth speakers. In terms of health, you can expect quiet calls, pleasant-sounding music and performance fidelity.
The membrane stands out for its surface qualities, among which is its excellent hydrophobicity. Water drops cannot penetrate the membrane, thus guaranteeing that your device is waterproof even in adverse environments. It also has incredibly high air permeability values, ≥ 4000 ml/min/cm² at 7Kpa, which ensures good ventilation, thus preventing the device from overheating and ultimately extending the life of these electronic products.
After special testing, the membrane's water pressure resistance was shown to withstand 40 KPa of pressure for 30 seconds, further confirming the membrane's reliability in protecting sensitive electronic components from external moisture and liquid intrusion. These properties make it an essential barrier for alarms, electronic sensors, and many other critical devices that require protection and performance.
Manufactured with operating conditions in a temperature range of -40 to 150 degrees Celsius in mind, this membrane is built to withstand extreme conditions, making it suitable for both indoor and outdoor applications. Whether you are in the hot desert or the frigid tundra, you’ll know your equipment will function properly.
Integrate this highly advanced PTFE membrane into your electronic products and experience a synergy of protection, performance and durability. Our cutting-edge solutions are designed to meet evolving technology challenges and give your products an edge.
