Our waterproof breathable membrane is designed for automotive electronics and consumer electronics that require reliable pressure equalization, waterproof protection, dust resistance, and long-term durability. Built with PTFE / PET fabric construction, this membrane offers an excellent balance of high airflow, strong water entry pressure, and moisture vapor transmission, helping protect sensitive components in sealed housings.
With IP68 protection, hydrophobic surface properties, and a wide operating temperature range, this vent membrane is an ideal solution for automotive sensors, lighting systems, battery housings, control modules, portable electronics, and outdoor electronic enclosures.
This waterproof breathable vent membrane is engineered to allow air and water vapor to pass through while blocking liquid water, dust, and external contaminants. It helps reduce internal pressure buildup caused by temperature fluctuations, altitude changes, or sealing conditions, improving the reliability and service life of electronic products.
The membrane features a PTFE / PET fabric structure with a hydrophobic surface, making it suitable for demanding automotive and consumer electronics applications where waterproofing and breathability are both essential. With typical airflow up to 2000 ml/min/cm² @ 7KPa and water entry pressure above 50 KPa, it provides stable venting performance while maintaining excellent environmental protection.
Its thin profile and strong interlayer bonding also make it easy to integrate into compact device structures and mass production processes.
Provides reliable protection against water and dust ingress, helping improve enclosure safety and long-term product reliability.
With minimum airflow >1300 ml/min/cm² and typical airflow 2000 ml/min/cm² @ 7KPa, the membrane supports fast and efficient pressure equalization.
Designed to repel water and help protect sensitive internal electronic components in harsh environments.
Water entry pressure is >50 KPa for 30 seconds, delivering strong liquid barrier performance.
WVTR >5000 g/m²/24h helps reduce condensation and moisture accumulation inside sealed enclosures.
With a thickness of 0.12 ± 0.05 mm and interlayer bonding strength >2 N/inch, it supports reliable assembly and stable performance.
Suitable for applications from -40°C to 125°C, meeting the demands of automotive and electronic products.
Meets ROHS requirements and is PFOA & PFOS free, suitable for global compliance needs.
We specialize in waterproof breathable membranes and venting solutions for automotive, electronics, packaging, and industrial applications.
Our membranes are produced under strict quality control to ensure consistency in airflow, waterproof performance, bonding strength, and thickness.
We support customized development based on your housing structure, installation method, and application environment.
We understand the performance requirements of sealed electronic products, including pressure balance, waterproofing, and durability.
We support overseas customers with efficient communication, sampling service, and stable bulk supply.
