PTFE air filter film is crystallized PTFE material in close to the melting temperature, extrusion film with quickly pulling speed, cooling after the film was the second extension drawing that the thin film has a three-dimensional structure. The diameter, thickness and porosity can be more according to the requirements in the tension adjustment, to produce the film can be applied to a variety of composite processing of the surface of the filter material, the filter accuracy is greatly improved, to intercept the dust on the membrane surface, easy cleaning fabric greatly prolongs the service life.
PTFE air purification filter membrane
This product uses the import PTFE resin, through a special process. To control the membrane pore size, pore size distribution, porosity and other technology. So that the membrane resistance, efficiency size can be adjusted freely. And with the import, domestic PET polyester nonwoven fabric glue dot transfer compound with or without glue high temperature hot melt composite. Products are widely used in industrial air filter and vacuum cleaner folded filter. Its main features are: easy cleaning, long service life, high air purification degree. Can reach European standard H11 H12 H13. The parameters are as follows:
Hole removal rate ％
