Electronic waterproof and breathable membrane‘s water pressure resistance refers to the pressure that the membrane can withstand when liquid intrusion occurs, and is often used to test the waterproof performance of the membrane . Different electronic products require different levels of protective films to meet their use requirements, so their water pressure resistance range is also relatively wide.
Generally speaking, the water pressure resistance of electronic waterproof and breathable membrane can be measured in millimeters of water column (mmH2O) or thousands of Expressed in Pascal (kPa). Among them, 1mmH2O is equivalent to 0.0098kPa. The following are some common water pressure resistance ranges:
1. 1000-2000mmH2O (9.8-19.6kPa): This water pressure resistance range can achieve basic waterproofing Function, it can prevent the intrusion of tiny water droplets or light rain, but it cannot withstand the intrusion of large amounts of liquid.
2. 3000-4000mmH2O (29.4-39.2kPa): This water pressure resistance range can prevent a moderate amount of splashing water and protect the inside of the equipment from moisture Intrusion, but the time of immersion in water should be limited to a short period of time.
3. 5000-10000mmH2O (49-98kPa): This water pressure resistance range can withstand longer periods of underwater immersion, thereby protecting the interior of the equipment from Intrusion of large amounts of moisture, such as when used on cameras used to shoot videos deep underwater or capture underwater sports.
It should be noted that the water pressure resistance of electronic waterproof and breathable membrane is not higher, the better. Excessively high water pressure resistance may cause the membrane material to be too hard, reducing its air permeability and affecting the heat dissipation of the equipment. Therefore, when choosing, you need to comprehensively consider multiple factors such as waterproofing, breathability, and heat dissipation to ensure that its quality and performance meet the requirements.
In short, Electronic waterproof and breathable membrane has a wide range of water pressure resistance. According to the needs of different electronic products, you can choose different ranges of water resistance. Pressure to meet its waterproof, dustproof, breathable and other requirements. When selecting, factors such as its breathability and heat dissipation also need to be comprehensively considered to ensure that its quality and performance meet the requirements.
