There are no hydrophilic groups or photosensitive groups in the macromolecules of polytetrafluoroethylene bubble-point membrane, so it is moisture-proof and has good weather resistance.
The bond energy of the C-F bond in the polytetrafluoroethylene molecule is high and stable. The van der Waals radius of the fluorine atom is larger than that of the hydrogen atom. The substitution of the fluorine atom causes ptfe to form a spiral structure. The fluorine atom forms a cylindrical shell, mainly because of this layer The inert spiral perfluorinated “shell” combined with the non-polar and crystalline structure of the polymer makes PTFE extremely resistant to chemical corrosion. It is called the “King of Plastics” and is resistant to all strong acids, strong bases, strong oxidants and salts. The class has no effect on PTFE, even under heating conditions, and it is also very stable to boiling aqua regia! ?The polytetrafluoroethylene bubble-point membrane made by mechanically stretching ptfe material can ensure the complete interception of impurities such as bacteria and has a large flux.
The material is resistant to high temperatures, strong acids and alkalis, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
