The main principle of ptfe bubble point filter material is to control the pore size of the membrane. The higher the bubble point, the smaller the pore size of the membrane, and the lower the bubble point, the larger the pore size of the membrane.
Bubble point membrane has a fibrillar microporous structure with a porosity of more than 88%. The pore size is small and uniform. There are 1.4 billion micropores per square centimeter, and the pore size ranges from 0.1 μm to 0.5 μm.
