Product Overview
The microporous ePTFE structure allows air exchange while preventing liquid water, dust and automotive contaminants from entering sealed electronic housings. It effectively eliminates condensation caused by temperature changes during driving conditions.
Core Advantages
- Wide operating temperature range from -40°C to +260°C for automotive environments
- IP67/IP68 waterproof and dustproof protection against rain, car wash and road dust
- Stable pressure equalization prevents deformation of sealed housings
- Resistant to oil mist, fuel vapor and chemical exposure
- Custom die-cut shapes and adhesive backing for compact automotive modules
Main Applications
- Automotive sensors (pressure, temperature, humidity)
- ECU electronic control units
- New energy vehicle battery systems
- On-board microphones and car audio systems
- Charging modules and power electronics housings
