PTFE filtration membrane used to kill germ is made by PTFE material in a sintering way. The range of aperture is from 1μ m to 0.01μ m. PTFE filtration membrane , with non-woven and woven fabric added , can be used to make kinds of filtration material for killing germ. PTFE filtration membrane can be used as folded filter, filtration material, etc. In the environment requiring killing germ and purification , PTFE filtration membrane can be used widely.

With strong hydrophobic property and application property to gas purification.

2. Resistance to strong acid and alkali ; Bearing high temperature; Good chemistry stability.

3. Being disposed to kill germ repeatedly under the condition of high temperature ; Having a long life of use

4. Saving energy and reducing consumption, and reducing the operating cost, wide serviceability.
