This is a very unique multi-metallized fabric. Of course you get good far field RF shielding: 65-80 dB tested over 30MHz to 1GHz.
But in addition, because of the Cobalt alloy top coating, this material offers remarkable magnetic shielding in difficult near field conditions.
Light weight (only 100 g/m2) and very flexible, tight taffeta weave.
Resistivity less than 0.1 Ohm/sq.
105cm wide, silver colored.
