Due to excellent performance, PTFE fine powder has become the important basic material in the field of modern thin film. The films made from PTFE possess excellent chemical stability, temperature resistance, electrical insulation,fiber-forming properties. Choosing PTFE fine powder for film production is a cost-effective choice.
The films made from PTFE fine powder appear outstanding functions and widely used in various sectors and fields. Details as below.
Waterproof and Breathable Films: used in clothing, outdoor products and other fields. The microporous structure allows water vapor to pass through while preventing water droplet penetration, providing waterproof, breathable, and windproof functions.
Air Filter Membranes: used in industrial flue gas filtration and air purification, these membranes offer precisely controllable pore size, effectively intercepting dust, bacteria and other substances. They boast high filtration efficiency and low operating resistance.
Liquid Filter Membranes: used in pharmaceutical, chemical, and water treatment industries for liquid filtration. They feature high throughput, high temperature resistance, and corrosion resistance, and can filter solutions containing strong acids and alkalis.
Electronic Insulation Films: used as insulating layers and separators in electronic equipment, providing reliable electrical insulation to ensure safe equipment operation.
New Energy Films: Such as proton exchange membranes in hydrogen fuel cells and lithium battery separators, these materials require extremely high chemical stability and temperature resistance. PTFE fine powder for film is an ideal choice.
