    What are the applications of waterproof breathable film?

    Building materials In the construction industry, waterproof breathable film is also known as waterproof vapor permeable film. Divided into standard waterproof breathable film, slope roof waterproof breathable film, slope roof universal waterproof breathable film.

    Automobile external lighting In modern society, the use of automobiles is common, and the transportation process will encounter different weather and road conditions. Headlights are always exposed to the external environment, dust, rain and snow, road debris and mud will affect the lighting of the headlights, thus affecting the safety of the vehicle during the driving process. The sudden drop in external temperature will lead to a drop in internal pressure, making the equipment easy to inhale pollutants and increase fog, and eventually cause lamp failure. The product can provide durable protection to the lights from the intrusion of external water vapor, dust, oil and other dirt. At the same time, the unique ventilation function of the product can exchange gas with the change of pressure, thereby reducing the pressure on the seal and extending the service life of the product.

    Potential problems with outdoor lighting fixtures: outdoor lighting covers are subject to changes in ambient temperature and pressure. Temperature changes, dust, dirt and moisture can have a considerable impact on the electronic components of outdoor lighting fixtures. For example, rainfall can cause a rapid cooling of the lamp casing, which can create a vacuum of 200mbar(3psi) or more inside the casing. This will seriously affect the performance of the internal components of the lamp. Solution: Maintain the balance of pressure inside and outside the shell by constant ventilation. After the waterproof breathable film is installed on the outdoor lamp cover, the pressure difference caused by the change of external temperature will no longer have a negative impact on the cover, because the waterproof breathable film can quickly balance the pressure inside and outside the shell when the ambient temperature and pressure change.
