AYNUO® Non-fluorinated waterproof and breathable membrane, the latest generation of breathable material that does not allow water penetration.

In recent years, as global environmental regulations have become increasingly stringent, green material technology has emerged as a focal point of industry attention. The European Chemicals Agency (ECHA) has proposed comprehensive restrictions on the production and use of per- and polyfluoroalkyl substances (PFAS), driving a pressing demand in the market for sustainable alternatives. Against this backdrop, the new generation of fluorine-free porous polymer membranes from Aiuyuo has been developed, offering an important solution that balances high performance with environmental responsibility.

Ⅰ. Introduction to the non-fluorinated waterproof and breathable membrane:

AYNUO® The non-fluorinated waterproof and breathable membrane is made from a high-polymer porous polymer that has been produced through a special process. This membrane achieves excellent overall performance without the use of any fluorinated compounds. It possesses outstanding breathability and water resistance, effectively blocking particulates such as dust, bacteria, and viruses, while balancing the pressure difference between the inside and outside of the sealed device to prevent deformation of the casing or failure of the seal due to changes in pressure differences.

II. Characteristics of the non-fluorinated waterproof and breathable membrane:

1. Effectively shields against moisture and dust, providing comprehensive protection for sensitive electronic components.

2. The use of breathable micro-pore structure allows for free air exchange, thereby balancing the internal and external pressure differences, effectively preventing the condensation of water vapor, avoiding fog formation, and significantly reducing condensation.

3. The built-in adaptive “breathing” mechanism intelligently balances internal and external pressures, ensuring the device is resilient to challenges posed by depth and temperature differences.

4. It has an extremely broad temperature tolerance range (-100°C to 200°C) and excellent thermal stability. Even in high-temperature environments, it can effectively resist acid and alkali corrosion, ensuring long-term reliability in harsh conditions.

5. It exhibits excellent compatibility with various manufacturing processes, enabling support for multiple mainstream fixing methods such as welding and adhesive bonding, thereby catering to the diverse integration needs across different application scenarios.

6. Strictly eliminate per- and polyfluoroalkyl substances (PFAS) to ensure that the products meet the most stringent environmental and health safety standards.

III. Technical parameters of the non-fluorinated waterproof and breathable membrane:

The non-fluorinated waterproof and breathable membrane comes in various models, allowing for selection based on specific needs. The breathability ranges from 200 to 3300 ml. Here is a detailed overview:

Note:

IP67: Submersion in water up to 1.0 meters for 30 minutes

IP68: Submersion for 30 minutes at a depth of 1.5 meters in water

IV. Applications of the non-fluorinated waterproof and breathable membrane:

Industry and electronics: battery explosion-proof valves, underwater equipment, sensors, automotive water pumps, waterproof connectors, etc.

Medical Devices: Artificial blood vessels, monitoring devices, etc.

Aerospace and Aviation: Waterproof and breathable valves, sealing and waterproof materials.
