Polytetrafluoroethylene (PTFE) material, commonly known as the “king of plastics”, is a polymer compound polymerized by tetrafluoroethylene. It has excellent low temperature resistance, alkali resistance, hydrophobicity and non-adhesion properties.
The PTFE microporous membrane prepared by the biaxial stretching process has a microporous structure of interwoven fibers. It has high porosity, small and uniform pore size. Therefore, the PTFE microporous membrane can be used with low resistance. Get higher power.
Application scale: (1) Air pollution filtration is widely used in pleated filter elements of vacuum cleaners and indoor air filter pleated filter elements. It has the characteristics of high power, easy cleaning, and washability.
(2) Industrial dust removal filter bags help power plants, cement plants, steel plants, etc. reliably control particulate matter emissions and purification.
The PTFE membrane dust removal filter bag can reliably capture particles to ensure near-zero emissions, has excellent dust stripping performance, and extends service life and stability.
(3) Filtration in medicine, food, bioengineering and other operations.
The membrane pore size is adjustable to obtain different bubble point pressures to meet different filtration precisions.
The membrane pores are evenly distributed to ensure the retention of bacteria and other impurities.
It has two types: hydrophobic and hydrophilic: Hydrophobic: used for gas filtration to achieve sterility, low temperature resistance, resistance to strong acids and alkali, wide chemical applicability, suitable for fermentation tanks, carbon dioxide, nitrogen, compressed air .
When used for gas filtration, it can intercept 99.99% of various phages, bacteria and particles above 0.02μm.
Hydrophilicity: Used for liquid filtration to achieve sterility, wide chemical applicability, resistance to strong acids and alkali, and high ozone intensity.
(4) Precision electronic products, lighting equipment, waterproof mobile phones and other fields.
Precision electronic products have requirements for waterproofing and breathability. On the one hand, they need to keep the air flowing smoothly. On the other hand, they need good waterproofness to prevent electrical components from getting damp. PTFE microporous membrane can meet these needs very well. Porosity ensures the flow of gas, and the fine pore size and hydrophobic properties prevent the entry of water droplets.
(5) Outdoor sportswear or equipment.
Excellent waterproof performance, can effectively isolate rainwater.
Excellent breathability, effectively eliminates sweat and maintains human body comfort.
Abrasion resistance and washability.
PTFE microporous membrane is waterproof, dustproof and breathable. In addition to being widely used in the fields of clothing fabrics and electronic equipment, it is also used in food packaging, building exterior walls, anti-haze screens and other fields.
