ＭＧnet Q&A

QWhat is the difference between this electromagnetic wave protective clothing made by companies other than MGnet?

AMaterials other than MGnet cannot be "washed". The shielding performance is lost after a few washes, so it is inappropriate to use them for anything other than "disposable protective clothing".
In addition, there are no other electromagnetic wave protective clothing products from our company that have undergone electromagnetic wave exposure tests or clinical trials using human dummies, so it is not possible to compare the differences.

QSilver corrodes when subjected to sulfidation or chlorination, but does this affect its durability?

AWhen silver is sulfurized, it becomes silver sulfide. When it becomes silver sulfide, its conductivity decreases, and its performance decreases. However, MGnet for EMC countermeasures is coated with conductive and rust-proof acrylic, so it has a stable electromagnetic shielding effect for more than 5 years unless it is in an abrasive environment.

QHow does it differ from ordinary electromagnetic shielding materials such as aluminum or copper metal films?

AAluminum and copper have an electromagnetic wave shielding performance of over 100 dB, and reflect 99.999% of electromagnetic waves. As a result, the effects of reflection and resonance become greater, causing unexpected electromagnetic interference in surrounding devices.
MGnet limits the shielding rate to 97% to 99% by the number of layers, uniformly reducing the impact on surrounding equipment and reducing electromagnetic interference.
Errors caused by electromagnetic interference in equipment do not require the electromagnetic waves to be reduced to zero; rather, the level of the electromagnetic waves can be reduced to a level where no errors occur. Therefore, materials with appropriate shielding performance for the purpose, such as MGnet or EMCscreen, are more suitable for EMC countermeasures than materials with too high shielding performance.

QIs the silver material used in MGnet a special kind of silver?

AIt is made of 99.9% pure silver. The surface of the MGnet for EMC countermeasures is treated with conductive anti-rust acrylic material for corrosion resistance.

QWhat does MG stand for?

AThe M stands for magnetic field and microwave, and G stands for guard.

QIs this product fire resistant, fire weak, or flammable?

ASilver fiber is made of nylon, so it is flammable. However, it is not flammable. Even if it does catch fire, it will just melt and will not spread. However, if the temperature exceeds 200℃, the fiber will turn into glass and become brittle.
