Excellent Physical Properties

High and low temperature test
The industry standard is: -30°C to +70°C, our Metal Mesh can reach -85°C to +85°C, and it can be used normally in extreme environments;
Environmental test: The test product functions normally at -80°C, 100°C (boiling water), and -235°C.

Cyclic bend test
Bending degree: from 0~90~180 degrees (cyclic bending), bending diameter: 4mm, 8mm;
After cycling 10k, 50k and 200k times, the resistance value of the display channel did not change.

Loop folding test
When the bending diameter is ≤4mm, and the bending angle is folded from 20 degrees to 180 degrees, the metal mesh can be used normally, and the folding touch can be realized.
