    Product Features and advantage

    1.Waterproof and Breathable: The ePTFE membrane combines the unique properties of being both waterproof and breathable. It forms an impenetrable barrier against liquids while allowing the passage of moisture and air, ensuring excellent protection without compromising performance.

    2.Pressure Differential Balance: The membrane maintains a balanced pressure differential between the internal and external environments of electronic devices. This prevents the entry of water and other contaminants while ensuring that internal pressure is adequately equalized.

    3.Chemical Corrosion Resistance: The ePTFE membrane provides outstanding resistance to chemical corrosion, protecting sensitive electronic components from the damaging effects of chemicals and solvents commonly encountered in various industries.

    4.High Temperature Resistance: Engineered to withstand high temperatures, the ePTFE membrane protects electronics from heat-related damage. It acts as an effective thermal barrier, maintaining device integrity even under extreme operating conditions.

    5.UV Protection: With its UV-blocking properties, the ePTFE membrane shields electronic devices from the harmful effects of solar radiation. This prevents degradation, yellowing, and performance deterioration, ensuring long-lasting device efficiency.

    6.Dust and Oil Resistance: The ePTFE membrane effectively blocks dust particles and repels oil, enhancing the longevity and reliability of electronic devices, especially in environments prone to dust accumulation or oil contamination.
