PTFE-based electromagnetic wave absorbing patch relies on the characteristics of the material to absorb electromagnetic waves. These electromagnetic wave energy is absorbed in the form of conduction loss, dielectric loss, and magnetic loss when passing through the wave absorbing patch, thereby purifying the electromagnetic environment and protecting electronic equipment Normal operation.
1) Strong resistance to salt spray, high and low temperature
2) High product strength
3) High heat resistance and thermal stability (-60℃~260℃)
4) Good absorbing performance
1) Wireless infrastructure equipment
2) Communication equipment
3) Portable electronic equipment
