AYNUO innovative materials help the hearing aid industry change

Hearing aids are an invaluable hearing aid for many people in modern life. However, due to the diversity and variability of the daily use environment, such as the influence of moisture and dust, hearing aids often face the problem of being polluted by the outside world. Fortunately, an innovative material, ePTFE waterproof and breathable membrane, is leading the transformation of the hearing aid industry.


 As a special material, ePTFE (expanded polytetrafluoroethylene) has excellent waterproof and breathable performance. This makes it the material of choice for hearing aid manufacturers to protect the electronic components inside hearing aids.


 Recently, a well-known European hearing aid manufacturer contacted AYNUO. They needed a reliable material that could meet the acoustic performance of the hearing aid while ensuring the protection level of the hearing aid.

 Based on long-term R&D and application experience in the field of ventilating products, AYNUO recommends the ePTFE waterproof and ventilating membrane with adhesive backing as the solution for customers.



 The ePTFE material has excellent waterproof performance, which can effectively prevent water and humidity from entering the interior of the hearing aid. This makes the hearing aids more durable in the face of wet conditions, reducing the risk of damage from moisture. Whether it’s an outdoor activity or a rainy walk, there’s no need to worry about moisture intrusion.



 The excellent air permeability of ePTFE membrane is also its unique feature. The microporous structure enables the ePTFE membrane to realize the smooth entry and exit of gas molecules, thereby ensuring good ventilation and heat dissipation of the electronic components inside the hearing aid. This is critical to maintaining the proper operating temperature of the hearing aid and preventing components from overheating. Even after long-term use, hearing aids can still maintain stable performance, providing consumers with a good hearing experience.



 The durability and chemical stability of ePTFE material is also one of the important reasons why AYNUO recommends it to customers. Hearing aids are often in contact with the skin and are exposed to various environments at the same time.  The ePTFE waterproof and breathable membrane can resist the erosion of most chemical substances, and can withstand common physical wear and tear, prolonging the service life of hearing aids.

 The waterproof and breathable membrane can also provide good acoustic performance for hearing aids. It can ensure the delivery effect of the sound signal, thereby maintaining the sound quality of the device.


 After many times of communication and testing, AYNUO finally customized a suitable ePTFE venting product for the customer to ensure that the customer’s hearing aid products can operate stably in various environments.


 Experience clear sound and protect your hearing, AYNUO makes life easier.
