ptfe film

1. PTFE film has high filtration efficiency, which can meet the filtration efficiency level requirements of sub high efficiency, high efficiency, and ultra high efficiency air filters.
Compared to other high-efficiency filtration materials, PTFE microporous membrane has a higher PF value and good filtration performance. The PF value represents an indicator of the balance between filtration efficiency and pressure loss. The larger the PF value, the better the filtration effect. The calculation formula is as follows:
PF value=- log (1-filtration efficiency)/pressure loss * 1000
Pressure loss unit: Pa, test flow rate: 5.3cm/s, particle size range: 0.1~0.2um
3. The membrane pore size is small, and the PTFE air filtration membrane material has undergone high-temperature heat setting treatment, resulting in a stable microporous structure. Therefore, it can effectively intercept dust particles under high wind speeds.
4. PTFE air filtration membrane material has strong hydrophobicity, low surface energy, and good non adhesion, making it easy to remove dust accumulated on the surface of the material. Therefore, it can be washed with water to restore performance, achieve reuse, and greatly extend its service life.
5. Surface filtration mechanism, which can easily remove accumulated dust through mechanical vibration or wiping.
