e-PTFE expanded polytetrafluoroethylene material. The material has a unique nano-hole structure, the surface is smooth and not adsorbed, and one side of the material contains high-viscosity adhesive, which can adhere to the surface of various products to protect the waterproof and breathable film from water, dust, salt, and corrosive liquids. Contacting with other pollutants, so that the waterproof and breathable membrane can still have reliable performance when exposed to harsh weather environments. Its waterproof and dustproof safety grade can meet the standards of IP65, IP66, IP67 and IP68, and can also withstand extreme temperature and ultraviolet radiation.

E-PTFE waterproof breathable film is used in the sealed shell, it can release high-pressure gas to balance the pressure inside and outside the shell, so that water droplets are not easy to form on the inner wall of the shell. When the E-PTFE dustproof breathable film is used in battery products, it can also effectively prevent the accumulation of harmful gases released by battery reaction. In addition to the above characteristics, we can also customize different waterproof and breathable film products according to customer requirements.
