The H13 grade high-efficiency filter material is a microporous film produced using polytetrafluoroethylene dispersion resin through special processes such as premixing, extrusion, calendering, and biaxial stretching.
The surface morphology of the microporous 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.
At present, clean rooms are widely used in industries such as precision machinery, semiconductors, aerospace, and atomic energy.
The cores of these filtration equipment are almost all made of H13 high-efficiency filtration materials.
Because the filtration accuracy of this membrane can reach U15 level (99.9995%) or even U17 level (99.999995%), it can fully meet the purification requirements of high-precision electronic product processing workshops such as semiconductors and chips.
Therefore, PTFE film is becoming more and more popular among people.
