Polytetrafluoroethylene (PTFE) material, commonly known as the “King of Plastics”, is a polymer compound polymerized by tetrafluoroethylene. It has excellent high temperature resistance, oxidation resistance, alkali resistance, hydrophobicity, and non-adhesion performance.
The polytetrafluoroethylene microporous membrane is prepared by a biaxial stretching process. It has a microporous structure with staggered fibers. It has high porosity and small and uniform pore diameter. Therefore, the polytetrafluoroethylene microporous membrane has a lower Higher efficiency can be obtained under resistance.
Application fields: (1) Air purification and filtration: It is widely used in pleated filter elements of vacuum cleaners and indoor air filters. It has the characteristics of high efficiency, easy cleaning, and washability.
(2) Industrial dust removal and filtration: Dust removal filter bags help power plants, cement plants, steel plants, etc. reliably control particulate matter emissions and pollution.
PTFE membrane dust removal filter bags can reliably capture particles to ensure near-zero emissions, have excellent dust stripping performance, extend service life and stability, thereby reducing costs.
(3) Filtration in medicine, food, bioengineering and other industries: the membrane pore size can be adjusted to obtain different bubble point pressures and meet different filtration precisions.
The membrane pore size is evenly distributed to ensure complete retention of bacteria and other impurities.
It has two categories: hydrophobic and hydrophilic: 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 intercept 100% of various phages, bacteria and particles above 0.02um.
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 waterproof and breathable requirements. On the one hand, they need to maintain smooth air and constant internal and external pressure. On the other hand, they need good waterproofness to prevent Electrical components are affected by moisture, and polytetrafluoroethylene microporous membrane can well meet such needs. The ultra-high porosity ensures the flow of gas, and the tiny pore size and hydrophobic properties prevent the entry of water droplets.
(5) Outdoor sportswear or equipment: excellent waterproof performance and can effectively block rainwater.
Excellent breathability, effectively eliminates sweat and maintains human body comfort.
Good wear resistance and washability.
Polytetrafluoroethylene microporous membrane has the characteristics of waterproof, dustproof and breathable. In addition to being widely used in the fields of clothing fabrics and electronic equipment, it also has certain applications in food packaging, building exterior walls, anti-haze screens and other fields. .
