Waterproof Breathable Membrane for Automotive & Consumer Electronics

High-Performance PTFE Vent Membrane with IP68 Protection

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.

Product Description

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.

Key Features & Benefits

1. IP68 Waterproof Protection

Provides reliable protection against water and dust ingress, helping improve enclosure safety and long-term product reliability.

2. High Breathability

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.

4. Strong Water Entry Pressure

Water entry pressure is >50 KPa for 30 seconds, delivering strong liquid barrier performance.

5. Excellent Moisture Vapor Transmission

WVTR >5000 g/m²/24h helps reduce condensation and moisture accumulation inside sealed enclosures.

6. Thin Yet Durable Structure

With a thickness of 0.12 ± 0.05 mm and interlayer bonding strength >2 N/inch, it supports reliable assembly and stable performance.

7. Wide Operating Temperature Range

Suitable for applications from -40°C to 125°C, meeting the demands of automotive and electronic products.

8. Compliant Material Solution

Meets ROHS requirements and is PFOA & PFOS free, suitable for global compliance needs.
