PTFE film is an environmentally friendly material. It is made of polytetrafluoroethylene (ptfe) material through special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching.
PTFE material has excellent high temperature resistance, high temperature resistance, low temperature resistance, alkali resistance, anti-aging, anti-oxidation, electrically insulated wire, hydrophobicity, non-toxicity, high lubrication, non-adhesion, weather resistance, resistance to chemicals and many other features.
Therefore, it is widely used in air filtration, aviation, electronics, electrical appliances, chemicals, machinery, construction, textiles, medicine and many other fields.
The main structure of polytetrafluoroethylene film: 1. The surface morphology of ptfe film is a spider web-like microporous structure.
Pores are formed between the microfibers, and the arrangement direction of the microfibers is basically parallel to the stretching direction; the junction of the fiber bundles is the node, which is formed by the entanglement of many microfibers.
2.PTFE film is an asymmetric film, and the micropore size is different on the front and back sides of the film.
3. The cross-sectional micropore size of the polytetrafluoroethylene film is larger than the micropore size on the surface, and the vertical and horizontal micropore sizes are also different, with the longitudinal micropores being larger than the transverse ones.
4. The cross-section of the ptfe film is a network structure. The three-dimensional structure of the pores has very complex changes such as network connectivity, hole nesting, and channel bending. There may be multiple micropores forming a channel, or it may be A micropore is connected to multiple channels.
