Protective Vents Membrane

Protective vent membrane is a thin film material having protective properties that is typically applied to the outside shell of various equipment or items to offer ventilation and protection. This film material has unique physical and chemical qualities that successfully prevent dust, water vapor, foreign matter, and other contaminants from entering the interior of the device while allowing ventilation and protecting the device's vital components from damage.

The protective vent membrane's functioning concept is based on gas molecules' diffusion and penetration. When the temperature or pressure inside the device rises, the gas inside diffuses to the outside via the tiny pores on the protective vent membrane, achieving the goal of ventilation. At the same time, because the holes of the protective ventilation layer are so small, dust, water vapor, foreign matter, and other contaminants are unable to enter the device through these pores, providing protection.
 

This film is often comprised of high-quality polymer materials with a microporous structure that allows air and gas to pass through while successfully preventing liquids and particulate debris from entering the device. They are intended to maintain the device's interior environment steady under a variety of environmental circumstances, including waterproof, dustproof, and shockproof. This film typically contains self-healing properties, which means that if it is broken externally, it may repair itself, ensuring that the device's sealing effectiveness is not compromised.
 

1. Good ventilation performance: It effectively ensures air circulation inside the device, which aids in heat dissipation and maintaining a normal working temperature.
2. Effective protection: It prevents dust, water vapor, foreign matter, and other contaminants from entering the device, protects important components from harm, and extends the gadget's service life.
3. Light and portable: It is often light and thin, does not increase the device's volume or weight, and is easy to transport and use.
4. Simple to install and maintain: The installation process is straightforward, and it can typically be fixed on the device by pasting, snapping, and so on, with low maintenance costs.
