PTFE bubble point membrane is a dense, smooth and porous film made by mechanical biaxial stretching using a special process.
When the pore size of the membrane is molded to 0.2-0.5UM, bacteria and blood can be isolated.
The main principle is to control the pore size of the membrane. The higher the bubble point, the smaller the pore size of the membrane. The lower the bubble point, the larger the pore size of the membrane.
Main features: Strong hydrophobicity, 375% higher resistance to water intrusion than ordinary polyvinylidene fluoride (PVDF) filter membrane.
Resistant to impact, back pressure and repeated steam high-temperature sterilization.
Used for gas filtration to intercept 100% of various phages, bacteria and particles above 0.02μm.
PTFE bubble point membrane is a polymer waterproof material.
From a production point of view, the technical requirements of PTFE bubble point membrane are much higher than those of ordinary waterproof materials. From a quality point of view, it also has functional characteristics that other waterproof materials do not have.
The porosity of the film can reach more than 85%, and the air can flow smoothly.
The membrane pore size is 0.2-3μm, which can effectively isolate water points, and the waterproof grade can reach IPX7 or above.
Protect electronic instruments from becoming unusable due to moisture or water.
Compared with other breathable filter materials, it has excellent air permeability. It is difficult to form a thick dust layer on the surface of the film, and the dust can be naturally peeled off.
