Types of Electromagnetic Waves

The environment with low-frequency electromagnetic waves may influence
people's nervous systems and causes the diseases such as insomnia and
melancholia, etc.

Low-frequency electromagnetic waves are not able to be isolated, only can
be conducted. Even the best electro-magnetic waves conductor in the USA
or Germany technology is not able to provide effective improvement on it.
This is the reason why electric power substation, high-voltage electric case
and signal generating station are always labeled with warning marks. As it is
no way to block low frequency electromagnetic waves, the best way is
keeping away from them.

The protection ability of our shield products to low-frequency electromagnetic
waves is maximum 90%.

Mid Frequency (60 – 300 MHz)/High Frequency (300 – 900 MHz)

Mid to high-frequency electromagnetic waves can cause pathological
changes to human cells as well heat-destroy to human body.

Ultra High Frequency (above 900 MHz)

Our shield products were designed to provide the protection against the mid
to ultra high-frequency electromagnetic waves, the protection ability within
the said range can reach 99.99%.
