    ■ The waterproof and dust-proof breathable film of Vorui Technology increases the reliability of your products and improves the product quality and image
          The waterproof and breathable film series products are made of a flexible and elastic microporous material - polytetrafluoroethylene (e-PTFE). The microporous material of polytetrafluoroethylene has high porosity, uniform pore size distribution, breathability, small friction coefficient, minimal adsorption, not only dust prevention, oil repellency, hydrophobicity, thermal stability, chemical medium corrosion resistance, UV resistance, etc., but also can continue to play a breathable role under - 40 ℃ -+150 ℃ when used at a wide temperature.
The surface filtration of Vorui waterproof and breathable membrane series is superior to deep filtration, with excellent filtration efficiency and dust prevention rate of 99.9%, which almost realizes zero dust emission. The surface is smooth without condensation and easy to remove dust. The barrier effect is good, and the service life is long. BAE series adhesive backed membrane is simple to install and easy to use, which can be installed by personnel and machinery. The BA series welding type is embedded into other product components or cavities through mechanical thermal welding, The single and two-way permeability diaphragm can be selected according to the protection level of the product.

■ Protection and breathability, fog elimination, simple installation and low cost
       BAE series · adhesive backed waterproof and breathable products can fully guarantee the air permeability while improving the waterproof (various liquids) capacity. In the case of large internal and external pressure difference, they can also be instantly balanced to prevent water liquid molecules from penetrating to the other side. The pressure inside and outside the balance sensor cavity can be prevented in the future. The BAE waterproof and breathable patch can be directly pasted on the sealing shell with simple installation.
       BA series · welded film cutting products can be directly welded on the installation plastic shell by hot welding or frequency welding. They are bidirectional water resistant and breathable, eliminating fog. They can continue to be breathable in extreme weather, maintaining internal and external balance. Applicable temperature range: - 40 ℃ ->120 ℃; The welded film waterproof and breathable product is easy to design and form with the plastic shell, with low cost and simple and convenient process. Reduce design cost and adapt to lean production and processing.
Protective products
       Voir ®  microporous membrane can be divided into BA welding type, BAE back glue type and pure membrane according to the process. The color and shape are optional. The single/two-way waterproof and breathable membrane with IP65 --- IP67 --- IP68 protection grade can also be customized according to the needs and environment.

Product features
1. The surface is smooth, the adsorption is small, and the dust prevention rate is 99.9%;
2. Hydrophobic and oil repellent properties, which can effectively prevent water and oil leakage;
3. The porous structure reduces the generation of salt crystals and prevents condensation;
4. Continuously ventilate and balance the pressure, reducing the bearing pressure of the shell sealing strip;
5. The protection grade reaches IP68, which can effectively protect sensitive parts;
6. Chemical inertia, corrosion resistance, UV resistance;
7. Insulation, high temperature resistance and aging resistance.
Installation recommendations

Scheme I: Manual installation
① Clean hands and the installation surface to be pressed (check whether the counterbore pressing surface is clean and tidy, and clean with alcohol if necessary);
② Align the adhesive backed patch with the surface of the mounting counterbore, and then press the patch on the edge of the mounting surface;
③ Press the adhesive backed patch on the mounting surface, and gently press the edge for about 1.5s;
Finally, make sure that the counterbore of the backing film is clean and tidy after pressing.

Scheme II: Mechanical installation
① Clean the welding apparatus and installation counterbore, place the product installation counterbore position on the welded diaphragm, and control the welding time of the apparatus to complete the installation.
