PMA was born from our own personal concern on discovering the latest science aboutelectronics radiation and how to protect you from electromagnetic radiation pollution.
Special Ferrite Absorbing Materials and Dozens of Rare Elements
Color & Pattern
Radiation Absorption Rate
Attenuation Rate Peak
8.4 * 5.4 cm
Material and theory: As the photo shown bellow, the card is built with 3 layers material inside, which include 2 layers of graphene and one layer of ferrite polymer in the middle. When the incident wage pass through the first grapheme layer, part will be reflected, part will be absorbed into the high magnetic conductivity ferrite layer, resonate and transform into heat. The rest will be reflected by the second layer of the grapheme and back, forming multiple reflection and heat transformation, so this kind of structure can maximumly reduce the electromagnetic radiation. In addition, according to the principle of electromagnetic wave transmission, it always flow low magnetic conductivity to a higher magnetic conductivity area (the ferrite polymer area), thus the electromagnetic radiation surrounding us will flow to the card. It creates a radiation protection area more bigger than the size of the card protecting us from harmful radiation.
Application: Pregnant women & fetus, children, adolescent, elderly and e-working group. Especially for people who often use cell phone, computer, or exposed in radiation environment. How to Use: keep in shirt pocket or hang in front of chest, or area you want to protect. Protection Area: Ideal protection area is within 60 cm radius.
