XINXIA-BT20D Waterproof Breathable Vent Membrane for Automotive & Consumer Electronics

High-Airflow ePTFE Vent Membrane with IP68 Protection

The XINXIA-BT20D Automotive & Electronics Vent Membrane is a high-performance ePTFE 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 membrane offers high airflow, strong water resistance, excellent moisture vapor transmission, and stable bonding strength, making it an ideal solution for automotive electronics, consumer electronics, sensors, battery housings, control units, lighting systems, and sealed enclosures.

For manufacturers seeking a dependable waterproof breathable membrane supplier, XINXIA-BT20D provides an excellent balance of protection, venting performance, and production compatibility.

Product Description

The XINXIA-BT20D vent membrane is engineered to allow air and moisture vapor to pass through while helping block liquid water, dust, and environmental contaminants from entering sealed housings. This helps reduce internal pressure buildup caused by temperature changes, altitude variation, and enclosure sealing conditions, improving the reliability and service life of sensitive electronic devices.

Made from PTFE / PET fabric with a hydrophobic surface, this membrane is especially suitable for sealed electronic products that require dependable waterproofing and efficient pressure equalization. With typical airflow of 2000 ml/min/cm² @ 7KPa, water entry pressure above 50 KPa, and IP68 protection, it delivers stable venting performance in demanding automotive and consumer electronics environments.

Its 0.12 ± 0.05 mm thin profile and interlayer bonding strength above 2 N/inch also make it easy to integrate into compact product structures and mass production assemblies.
