An IP67/IP68 waterproof membrane is a microporous ePTFE film designed to protect sealed enclosures from water, dust and pressure buildup. Rated IP67 (1m/30min) or IP68 (continuous immersion), these membranes are widely used in automotive sensors, outdoor lighting, industrial electronics and TWS audio devices.
