The porosity of ptfe gray membrane can reach 80%~90%, and has been processed by high-temperature heat setting. The microporous structure is stable and can effectively intercept dust particles. Moreover, its pore size is small and uniform, and its surface filtration mechanism makes it easy to remove dust and is hydrophobic. It has strong resistance, low surface energy, and good non-adhesive ability. It can effectively remove dust accumulated on the surface. Washing with water or backflushing can restore the performance and greatly extend the service life. The filtration efficiency can reach 99.999995%.
