feature: 1. Naturally hydrophobic PTFE membrane with excellent porosity, high flow rate 2. Absolute rating, filtration efficiency≥99.99%, Up to 0.01 micron in gas sterile filtration 3. Low pressure drop and long service life 4. Wide chemical compatibility, resistant to
2018/11/8 · While hydrophobic membrane filters are ideal for air and gas filtration, they are not suitable for filtering aqueous solutions. Hydrophilic membrane filters, on the other hand, are commonly used for clarification and sterilization of water-based fluids but are not typically used for venting applications. To conceptualize the forces contributing
ePTFE liquid filtration membrane is made of PTFE resin, which is specially processed, biaxially stretched, and made into a hydrophobic film of polytetrafluoroethylene. Through special chemical and physical modification, the original hydrophobic Angle of 34ºC was modified to 122ºC, so that the membrane has the characteristics of high interception rate of liquid through particles above 0.1um.
2019/8/8 · The hydrophobic membranes showed good thermal efficiency (71 ± 2% at 60°C) to represent the highest values achieved in MD thus far. In total, the results suggested the larger pore size and wider
ePTFE liquid filtration membrane. ePTFE liquid filtration membrane is made of PTFE resin as a raw material, and is made into a polytetrafluoroethylene hydrophobic film by a special process and biaxial stretching, and then the original hydrophobic angle is changed to 34 ° C by special chemical and physical modification, thereby the membrane has
PTFE Unlaminated Membrane Filters, Hydrophobic, 3 Micron, 47mm, 100/Pk Unlaminated PTFE Membrane Filter Applications Chemicals, Petrochemicals,
PTFE membrane filters have an excellent chemical compatibility (pH 1 to 14), so that they are also used for the filtration of solvents and acids, to which other filter types are not resistant. Moreover they can be used to filter aqueous solutions as well, but because of their hydrophobic characteristics, they must be pre-wetted with ethanol or methanol before the filtration of aqueous media

Titan3 PTFE (Hydrophobic) Syringe Filter 0.45 µm, 30 mm, with Pre-Filter, 100 Pk. Diameter (Metric) 30 mm. Diameter (Metric) Membrane.
2021/6/8 · Polypropylene membrane is non-toxic and can be widely used in medicine, chemical industry, food, beverage and other fields; Hydrophobic, especially for gas filtration. 5. Polyethersulfone (PES) characteristics: the microporous membrane made of polyethersulfone is hydrophilic, with the characteristics of high flow rate, low dissolved matter and good strength.
The hydrophobic PTFE membrane filters are made of polytetra-fluorethylene (PTFE) only and are therefore permanently hydrophobic. Unlike hydrophilic filter types, they are not wetted by air humidity.
Polytetrafluoroethylene (PTFE) is increasingly used in membrane applications due to its excellent thermal stability, resistance to chemical degradation and strong hydrophobicity. However, it is difficult to prepare high flux membranes by conventional technology due to
2020/7/17 · Cellulose acetate membrane filter is non-toxic and can be widely used in medicine, chemical industry, food, beverage, and other fields; it is hydrophobic, and it is particularly good for air filtration. 3. PES – polyethersulfone (aqueous membrane) Features of pes
The hydrophobic PTFE membrane filters are made of polytetra-fluorethylene (PTFE) only and are therefore permanently hydrophobic. Unlike hydrophilic filter types, they are not wetted by air humidity.
