WOREMOR WMF200: Magnetic Shielding Film

WOREMOR WMF200: Magnetic Shielding Film for LF and HF Radiation

$35.99 USD

WMF200 is a specialized magnetic shielding film made from an amorphous cobalt alloy, designed to shield against Low-Frequency (LF) and High-Frequency (HF) radiation. It is easily cut, allowing you to create customized shapes and sizes to fit any area, and is also highly resistant to corrosion, even when exposed to humid temperatures.

The attenuation of the material remains constant at 40 dB at 1 GHz, even when under high stress. The cobalt strips makes the WMF200 very flexible, while still remaining solid so that it can keep its shape. Since these strips are so thin and thus quite sharp, the film is laminated to provide protection; it is this lamination that also prevents corrosion.

Processing
It can be difficult to glue the material without causing creases, and so it may be best to cover the area with solid wall coverings. When using the film on walls, ceilings and floors, we suggest that you use a highly viscous adhesive which adheres to non-absorbent substrates. First, smoothen the glue, then lay up the film, and finally apply it with a pressure roller or similar tool. The sheets should overlap, and then can be painted over if you so chose.

Grounding
WMF200 is electrically isolated. In order to ground the film, the strips must be screwed with a chopper disk which penetrates the plolyester.
