Product FeaturesPTFE microporous filter membrane is a microporous film made of polytetrafluoroethylene as raw material, using a special process, by extrusion, calendering, biaxial stretching and other methods. PTFE membrane can be divided into clothing membrane, air filter membrane, purification (bubble point) membrane, electronic (waterproof and breathable) membrane, cable membrane, sealing tape and so on.

Classification and application of PTFE membrane:1. PTFE clothing film is a microporous film made by biaxial stretching method using the pore-forming characteristics of PTFE plastic resin.Excellent waterproof performance, can effectively block rain. Good air permeability, effective elimination of sweat, to maintain human comfort. Good abrasion resistance and washing resistance.After being compounded with other fabrics, it is widely used in military clothing, medical clothing, leisure clothing, fire protection, anti-virus, immersion operations and other special protective clothing, outdoor sports clothing, shoes, hats, gloves and other accessories, as well as sleeping bags, tents, rain gear and other materials.
 

2,PTFE air filter membraneThe use of PTFE membrane microporous structure stability, low surface energy, chemical resistance, breathable impermeable, air permeability, flame retardant, high temperature resistance, strong acid and alkali resistance, non-toxic and other characteristics, can be used for atmospheric dust removal, air purification and so on. The product made of the membrane has high filtration efficiency, up to 99.99, nearly zero emission; low operating resistance, fast filtration speed; long service life, reusable, thereby reducing operating costs. Mainly used in chemical industry, iron and steel, metallurgy, carbon black, power generation, cement, waste incineration and other industrial furnace flue gas filtration.

3,PTFE purification (bubble point) membrane

The pore size of the membrane is adjustable, and the pore size of the membrane is small (0.05~0.45 μm), which can obtain different bubble point pressure and meet different filtration accuracy.

The uniform pore size distribution of the membrane ensures complete retention of impurities such as bacteria.

Extensive chemical applicability, biological safety and pyrogen control.

Hydrophobic and hydrophilic two categories: Hydrophobic: used for gas filtration to achieve sterility, large flux, high temperature resistance, strong acid and alkali resistance, wide chemical applicability, suitable for fermentation tanks, carbon dioxide, nitrogen, compressed air. When used for gas filtration, it can reach 100% retention of various bacteriophages, bacteria and particles above 0.02um. Hydrophilicity: used for liquid filtration to achieve sterility, wide chemical applicability, strong acid and alkali resistance, high ozone strength.

Biosafety: After 100% integrity test, it has reached the requirements of HIMA bacterial interception test in the United States.

Widely used in medicine, food, biological engineering and other industries filtration;

4. Electronic (waterproof and breathable) membrane
Electronic waterproof and dustproof breathable membrane with polytetrafluoroethylene as raw material, after puffing, calendering, biaxial stretching to form a microporous film.
1) The fibers are arranged in a staggered structure, the porosity of the film reaches more than 85%, and the air can flow smoothly.
2) The pore size of the membrane is 0.1-1μm, which can effectively block water droplets, and the waterproof level reaches IP67 ~ 68.
3) The membrane has good rigidity, moderate density and small sound insulation and sound loss.
The film is waterproof, dustproof, anti-oil and other characteristics, suitable for all kinds of handheld electronic equipment, precision electronics, solar equipment, chemical and medical equipment and other applications
