China Factory Suppliers Waterproof and Breathable E-PTEF Membrane Gas Permeable Air Vent Plug
Product Description
Outdoor self-adhesive protective breathable membranes are constantly exposed to harsh environments such as heavy rain, dust, sand and strong winds. Under changing environmental conditions, pressure builds up within the sealed housing, which stresses the seal. Over time, pressure can cause seals to fail, allowing water, corrosive liquids, salts and particles to enter the case and damage the electronics inside.
Self-adhesive protective breathable films are the leading solution for protecting sensitive electronic equipment. Self-adhesive protective breathable membrane allows air to move freely in and out of the sealed enclosure, equalizing pressure and reducing condensation. At the same time, they provide a long-lasting barrier to protect electronic devices from contamination. The result is improved reliability, safety and product life of sealed electronic devices.

Frequently Asked Questions
How do self-adhesive protective breathable membranes protect electronic equipment?
They allow air to move freely in and out of the sealed enclosure, which equalizes internal pressure and reduces condensation. Simultaneously, they act as a long-lasting barrier to prevent water, corrosive liquids, salt, dust, and sand from entering and damaging internal electronics.
What is the IP rating and temperature resistance of the HR-WB-12 model?
The HR-WB-12 model features an IP67 rating and is designed to withstand extreme temperatures ranging from -40℃ to +150℃, making it suitable for high-temperature applications.
What materials are used to manufacture the breathable plug and cap?
The breathable membrane is made of expanded polytetrafluoroethylene (ePTFE) and polyester. The canning structure is constructed from polypropylene, and the internal sealing components are made of thermoplastic elastomer.
What is the airflow performance of the breathable membrane?
The membrane provides an airflow rate of 2300ml/min/cm² under a pressure difference of 70 mbar, ensuring efficient pressure equalization.
What are the standard packaging and delivery specifications?
The product is packaged with 200 pieces of car vents per bag, and 25 bags per box. The packaging size per batch is 39*33*23 cm, with a gross batch weight of 9.000kg. The minimum sales unit is in multiples of 5000.
