Polytetrafluoroethylene bubble point film is a polymer compound polymerized from tetrafluoroethylene. It is prepared through a biaxial stretching process to obtain polytetrafluoroethylene (PTFE) material, commonly known as the “King of Plastics”.
It has a microporous structure with staggered fibers, high porosity, and small and uniform pore diameter.
It has properties such as high temperature resistance, oxidation resistance, alkali resistance, and hydrophobicity.
?PTFE bubble point film has strong hydrophobicity, non-adhesiveness, corrosion resistance, thermal stability and good mechanical properties. Therefore, it can be washed with water to restore its performance and achieve repeated use, greatly extending its service life and saving money. cost.
Its characteristics are breathable and impermeable.
The microporous membrane itself has countless interconnected micropores. Its pore size is very small (about 0.01~10 microns) and can only pass through water vapor molecules with a particle size of about 0.1nm. However, for any raindrops or water droplets, due to their particle size The path is too large to pass.
It has hydrophobic and hydrophilic properties and is used in medicine, food, and bioengineering.
