ePTFE waterproof breathable membranes provide essential pressure equalization and protection for modern mobile phones and electronic devices. With air flow rates of 3000-5000ml/min/cm² at 7Kpa pressure, these membranes enable sealed devices to maintain optimal performance in diverse environmental conditions.

• Balances internal and external pressure differentials to extend sealing structure lifespan
• Maintains water vapor balance to reduce condensation and lens fogging
• Preserves acoustic performance while providing IP67-IP68 waterproof protection
• Prevents dust ingress with level 6 dustproof efficiency
• Resists chemical exposure including soapy water, alcohol, and coffee

• Natural hydrophobic breathability with extended service life
• Chemically inert with resistance to acid and alkali corrosion
• Level 6 dustproof efficiency protecting internal components
• Resistant to common liquids including soapy water, alcohol, and coffee
• Wide temperature resistance from -40°C to 130°C
• Enables acoustic components to vibrate freely for perfect sound quality

• Waterproof mobile phones and smartphones
• Wearable electronic devices
