Application of Polytetrafluoroethylene (PTFE) Membrane

Polytetrafluoroethylene (PTFE) membrane filter is made of polytetrafluoroethylene, which is expanded and stretched to form a microporous membrane. PTFE membrane filter is laminated on various fabrics or papers by a special process on the substrate, it becomes a new type of filter material with small and uniform pore size and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria. To achieve the purpose of sterilization and purification and air circulation.

Hydrophobic PTFE membrane filters are made of PTFE, which is completely natural and permanently hydrophobic. Even under a very low pressure difference, it can ensure the unobstructed passage of moist air or other gases, while the aqueous solution cannot pass through. Its performance is just the opposite of that of the hydrophilic membrane. Hydrophobic PTFE membrane filter can effectively filter all kinds of strong corrosive chemicals or samples.

The polytetrafluoroethylene (PTFE) membrane is an inlet membrane, a hydrophobic membrane filter, which is treated with ethanol or isopropanol to become a hydrophilic membrane filter. The hydrophobic membrane cannot be naturally wetted, and the hydrophilic membrane can be naturally wetted.

Polytetrafluoroethylene (PTFE) membranes are resistant to high temperatures, strong acids, strong alkalis, organic solvents, and oxidants. PTFE membranes and hydrophilic PTFE membrane filters are chemically compatible and resistant to most chemical solvents. PTFE membrane is chemically stable and inert, suitable for chemically corrosive organic solvents, aqueous solutions, and gases, and has resistance to most acids, alkalis, and solutions.
