PTFE film

'Hushen' brand PTFE micropore film adopts special two-way drawing process to get the light and flexible film. The thickness is 0.025mm, aperture ratio 82%, maximum diameter or hole 0.2μm, has 9 billion micropore in every Sq. In, the hole diameter of the micropore is 20 times of moisture molecule, 20,000 times smaller than water-drop, thus it has the excellent water-proofing, moisture permeable, wind-proofing, warm and corrosion resistant properties, it is the ideal material for manufacturing of high-ranking composite fabrics. It is also extensively applied in construction, water treatment and membrane permeation fields for its water pressure resistance and special microporosity. The product implements PTFE film Q/HS004-2000 technical standard.
