Frequently Asked Questions
What waterproof rating do your membranes achieve?
Our ePTFE waterproof breathable membranes achieve IP67 and IP68 protection grades. They withstand immersion at 1 meter depth for 30 minutes (IP67) and continuous submersion (IP68), while maintaining stable airflow for pressure equalization.
Can you provide custom sizes and die-cutting shapes?
Yes, we offer full custom die-cutting services. We can produce membranes in any size or shape according to your specifications, including round, rectangular, and complex custom geometries. Our Class 10,000 cleanroom ensures precision cutting for production volumes.
What is the minimum order quantity (MOQ)?
We support both prototyping and mass production. Free samples are available for testing with 3-5 working days delivery. For mass production, MOQ is flexible depending on the product specification and can be discussed based on your project requirements.
What industries and applications do your membranes serve?
Our membranes are widely used in automotive electronics, lithium batteries, smart wearables, consumer electronics, LED lighting, medical devices, and industrial sensors. Applications include speaker acoustic vents, pressure balance vents, microphone waterproof membranes, and battery venting solutions.
How long is the delivery time for samples and mass production?
Free samples are delivered within 3-5 working days via express shipping. Mass production typically takes 7-15 working days depending on order quantity and customization requirements. We provide one-stop technical support from sample testing to mass production.
