China Factory Suppliers Hydrophobic E-PTEF Membrane Gas Permeable Air Vent Cap - Waterproof & Breathable Protection
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
QWhat is the primary function of the self-adhesive protective breathable membrane?
It allows air to flow freely in and out of sealed enclosures to equalize pressure and reduce condensation, while creating a durable barrier that protects sensitive electronics from water, dust, and other contaminants.
QWhat are the key technical specifications of the HR-WB-12 model?
The HR-WB-12 model features an IP67 rating, temperature resistance ranging from -40℃ to +150℃, an inlet water pressure threshold of -120 mbar (>1 meter), and is certified under ISO9001 standards.
QWhat 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 components utilize thermoplastic elastomer.
QHow does the membrane prevent seal failure in outdoor environments?
By equalizing internal housing pressure caused by changing environmental temperatures and winds, the membrane reduces physical stress on the housing seals, preventing leaks and moisture ingress.
QWhat are the packaging and order details for bulk delivery?
The products are packaged with 200 pieces of car vents per bag and 25 bags per box. The standard sales unit is in multiples of 5000, with a gross batch weight of 9.000 kg and package dimensions of 39*33*23 cm.
