Description: EPTFE is a new waterproof and breathable material The waterproof and breathable membrane has three functions: 1. waterproof: micro pores of 0.1-1.0, with pore diameter less than 10000 times that of water droplets, making it impossible for water to pass through, effectively protecting sensitive parts, avoiding liquid erosion, and improving product service life 2. air permeability: the pore diameter of the micropore is 700 times larger than that of the water vapor. It is waterproof and allows the air to pass smoothly. It can effectively dissipate heat, prevent the inner wall of the product from fogging, and balance the air pressure inside and outside the space. 3. dust prevention: the microporous channels form a network three-dimensional structure in the membrane, with uniform and dense microporous distribution, so that the dust is blocked to achieve effective dust prevention effect, and 0.1 micron particles can be captured. Main functions: 1: Effectively block water, salt and other corrosive liquids, and make sensitive parts of the equipment safely leak outdoors. 2: Air permeability can be quickly restored after contact with water, oil and other liquids. 3: The dense and uniform micropore distribution can effectively block dust while being waterproof and breathable. 4: Balance the pressure, prevent the air and water around the sealing parts from entering the machine body, and protect the sealing integrity. 5: Protect the parts from the weather and withstand the immersion of water and other liquids. 6: Make the protected parts easy to clean, free from corrosive pollutants, and ensure the performance and service life of the parts. 7: UV resistant, with strong chemical inertia. 8: Thin and light, with good concealment, it brings convenience to design and production.
