Polytetrafluoroethylene bubble film, also known as ptfe bubble film, forms a microporous film after expansion and stretching.
It has a fibrillar microporous structure, the porosity can reach more than 88%, the membrane porosity is high, the pore size is small and uniform, therefore, the membrane can achieve higher efficiency at lower resistance, not only can It effectively intercepts dust particles, with the highest accuracy reaching H14 level (99.995%) and above, and allows the vacuum cleaner to maintain low energy consumption, and the material can be washed with water to restore performance and be reused, greatly extending the service life, which greatly Cost reduction.
