High-Airflow ePTFE Vent Membrane with IP68 Protection

The XINXIA-E20WO-E Automotive & Electronics Vent Membrane is a high-performance ePTFE oleophobic and hydrophobic breathable membrane designed for applications that require reliable pressure equalization, waterproof protection, dust resistance, and long-term durability.

Built with PTFE / PET fabric construction, this vent membrane offers high airflow, strong water entry pressure, and excellent moisture vapor transmission, making it an ideal solution for automotive electronics, consumer electronics, sensors, battery housings, lighting systems, portable devices, and sealed enclosures.

If you are looking for a dependable waterproof vent membrane supplier for automotive and electronic products, XINXIA-E20WO-E is an efficient choice for both protection and production integration.

Product Description

The XINXIA-E20WO-E vent membrane is engineered to protect sensitive components from water, dust, and environmental contaminants while allowing air and water vapor to pass through. This helps reduce internal pressure buildup caused by temperature changes, altitude variation, and sealing conditions, improving the reliability and service life of enclosed electronic products.

Made from PTFE / PET fabric with oleophobic and hydrophobic surface properties, this membrane is suitable for demanding environments where both liquid resistance and breathable performance are required. With typical airflow of 2500 ml/min/cm² @ 7KPa, water entry pressure above 70 KPa, and IP68 protection, it offers an excellent balance of airflow and enclosure protection.

Its 0.12±0.05 mm thin profile also supports compact product design and efficient integration into modern automotive and consumer electronic housings.
