Product Overview

Waterproof breathable membrane works

Waterproof breathable membrane working principle Waterproof and breathable   membranes are made of breathable hydrophobic polytetrafluoroethylene(EPTFE)and   treated with patented technology, which makes the film have the property of   oleophobic, which greatly improves the durability of the breathable film. Even   after prolonged exposure to outdoor and industrial environments, repeated   exposure to oils, chemicals, detergents, and other low surface tension liquids,   the superior performance of waterproof, dust proof, breathable membranes remains   the same.

Breathable and protective

Waterproof and breathable products are air-permeable solutions that integrate   balance pressure, battery hydrogen permeability and sound transmission. They can   economically and effectively solve problems such as water vapor condensation,   pressure changes,and adverse environmental impacts during the use of equipment.   Waterproof and breathable products are effective in blocking dust and dirt from   the equipment while ensuring that the equipment maintains good air   permeabilityunder changing environmental conditions thereby avoiding pressure   build-up in the equipment due to air accumulation resulting in a housing seal   Damage causes internal sensitive electronic components to suffer from water and   dust. waterproof and breathable products can provide unmatched and powerful   protection for sensitive electronic devices.

Balance pressure and eliminate condensation

All electrical and electronic enclosures working outdoors are subject to   temperature fluctuations and the effects of wind rain, and sunlight. For   example, a sudden drop in temperature caused by a storm may cause a 200 m bar (3   psi)vacuum inside the housing, eventually drawing air and water vapor into the   equipment. Once the water vapor enters the closed casing, if it is not removed   in time, it will have corrosive effect on sensitive electronic components.   Waterproof and breathable products help to balance the pressure inside and   outside the housing, prevent air and moisture from entering the housing through   the sealing strip, and can effectively protect the integrity of the sealing   strip. The breathable membrane also accelerates the diffusion of ter vapor,   thereby reducing the accumulation of water vapor inside the shell and rapidly   eliminating the condensation within the shell.
