PTFE film  is a microporous film produced using polytetrafluoroethylene dispersion resin through special processes such as pre mixing, extrusion, rolling, and biaxial stretching. It is divided into clothing film, pu micro waterproof film, filter film, and purification film. Do you understand the classification and application of polytetrafluoroethylene films? Let's take a look at the classification and application of polytetrafluoroethylene film.

PTFE Clothing film

A microporous film made by using the pore forming properties of polytetrafluoroethylene plastic resin and biaxial stretching method. The surface of the membrane can reach over one billion micropores per square centimeter, with each micropore having a diameter of 0.1 μ M-0.5 μ m) Specific water molecule diameter (20 μ M-100 μ m) Several hundred times smaller than water vapor molecules (0.0003 μ M-0.0004 μ m) It is tens of thousands of times larger, allowing water vapor to pass through, while water droplets cannot. By utilizing this microporous structure, excellent waterproof and moisture permeability can be achieved; In addition, due to the extremely small size and irregular longitudinal bending arrangement of the holes, the wind cannot pass through, thus possessing wind resistance and warmth retention characteristics. After being compounded with other fabrics, it is widely used in military clothing, medical clothing, leisure clothing, special protective clothing for fire fighting, poison prevention, water immersion operations, outdoor sports clothing, shoes, hats, gloves and other accessories, as well as sleeping bags, tents, rain gear and other materials.

PTFE Air filtration film

Utilizing the unique node fiber properties, smooth surface, chemical resistance, breathability, high permeability, flame retardancy, high temperature resistance, strong acid and alkali resistance, and non-toxic properties of polytetrafluoroethylene microporous membrane, it can be used for atmospheric dust removal, air purification, and other purposes. The product made of this membrane has high filtration efficiency, up to 99.99%, close to zero emissions; Low operating resistance and fast filtration speed; Long service life, reusable, thereby reducing operating costs. It is mainly used for flue gas filtration of various industrial furnaces in chemical industry, steel, metallurgy, carbon black, power generation, cement, Incineration, etc. PTFE filtration membrane, with a pore size controlled between 0.2 and 15 μ Between m, the porosity can reach over 85%.

PTFE Air purification film

Air purification membrane is a type of microporous film formed from polytetrafluoroethylene as raw material after expansion and stretching. This film is coated on various fabrics and substrates using a special process to become a new type of filtration material, with a small pore size (0.05-0.45 μ m) It is evenly distributed and has a high porosity. While maintaining air circulation, it can filter all dust particles, including bacteria, to achieve purification and ventilation. It is widely used in fields such as pharmaceuticals, biochemistry, microelectronics, and laboratory consumables.
