Polytetrafluoroethylene bubble film, also known as ptfe bubble film, forms a microporous film after expansion and stretching.
It has a fibrillar microporous structure and the porosity can reach more than 88%.
The PTFE bubble-point membrane has high porosity and small and uniform pore size. Therefore, the membrane can achieve higher efficiency at lower resistance. It can not only effectively intercept dust particles, but the highest accuracy can reach H14 level. (99.995%) or above, it can also keep the energy consumption of the vacuum cleaner low, and the material can be washed to restore its performance and be reused, which greatly extends the service life, which greatly reduces the cost.
