Where does the material come from?
- In space travel a protective material is often used to stop the crew and the sensitive technical equipment on board from being exposed to dangerous electromagnetic rays.
- The use of copper and nickel has proven particularly effective to this end. Aerospace engineers coat spacecraft and satellites with materials that are made of a combination of copper, nickel and polyester in order to ward off cosmic rays.
- As you can see on picture below, the material is made principally from a combination of copper, nickel and tear resistant polyester. This material has something on offer for every single household. Everyone is in a position to protect his, or her, body from the harmful effects of electromagnetic radiation.

The material used in space travel doesn’t just work in space but it also works on planet earth.
Hence, it is perfectly possible to block harmful
Wifi and mobile signals.
