It is a high-performance polymer processed to create billions of microscopic pores. These pores are small enough to block liquid water and dust particles while remaining large enough to allow air and water vapour to pass through freely — making it ideal for protecting electronics and other sensitive components.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can these membrane stickers be used outdoors?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The EPTFE material offers strong UV resistance and chemical inertness, making the stickers well-suited for outdoor applications such as exterior lighting, outdoor cameras, automotive sensors, and weatherproof enclosures.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How are the stickers applied?\u003c\/h4\u003e\n\u003cp\u003eA: Each sticker features a pressure-sensitive adhesive backing. Simply peel and apply over ventilation holes or ports on your device or enclosure. Ensure the surface is clean and dry before application for the best adhesion.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Will the breathability be affected after getting wet?\u003c\/h4\u003e\n\u003cp\u003eA: No. One of the key advantages of EPTFE membranes is that their air permeability is quickly restored after contact with water, oil, or other liquids.
