Product Application : IP67 IP68 (2m*30min)


With consumer electronics growing more popular by the day, the mobile phone industry has entered a highly competitive phase.


Diversified application scenarios have given rise to a strong demand for waterproof mobile phones, which has gradually become the standard for flagship models in the industry. At present, Top 3 mobile phone brands have achieved the waterproof level of IPX7 and IPX8 (1.5-2m) for their flagship models. According to industry forecast, most mobile phones are expected to be waterproof in the next 3 to 5 years.


Also, consumers’ need for attractive appearance is pushing mobile phones to be ever thinner. This means for compact space to contain multiple electronic components that release a lot of heat, and when heat brings temperature rise, pressure will start building inside the casing, and eventually cause casing deformation, which threatens product reliability, sound quality and consumer experiences.


With its simplistic adhesive installation methods and natural hydrophobic features, IPRO pressure vent helped mobile phones to achieve IPX7 and IPX8 waterproof levels, allowing the phone to be emerged at 1-2m depth for 1-2 hours without breaking.


Stretching processing creates porous structure, making IPRO pressure vent excels in air permeability. By micropores with a diameter between 0.1 and 10 μm, dust is blocked base on the product’s strong filtration capabilities.


With both water and dust proof functions, phones will be safer wherever they are used, be it at the beach, in the bath or in the rain.

Key Features
  • Pure natural hydrophobic and permeable performance, with long service life;
  • Chemical inertness, resistant to acid and alkali corrosion;
  • Dust-proof Rating: Up to Level 6, preventing dust from entering the machine and damaging the components;
  • Resistant to splashes of soapy water, alcohol, coffee, etc.;
  • Operation Temperature: -40℃-105℃.
