What is the main structure of PTFE microporous membrane?

Polytetrafluoroethylene microporous membrane is an environmentally friendly material. It is made of polytetrafluoroethylene (ptfe) material through special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching.

The surface morphology of the 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.
