China Suppliers Factory Hydrophobic E-PTFE Membrane Gas Permeable Plug Air Vent - Waterproof & Breathable Cap
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.
