EMF Shielding Fabrics



"Near Field Magnetic RF Shielding"

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 radiofrequency magnetic shielding in difficult near field conditions (80 dB or better!). This material even shields 70-80 dB over 24-40 GHz! Great for shielding Cellphones, Laptops and iPad radiation.


CobalTex Great for reducing interference between tightly placed components. Light weight (only 100 g/m²) and very flexible, tight taffeta weave. Resistivity less than 0.1 Ohm/sq. 42 inch wide, silver colored.

"Shielding Fabric With Hot Melt Adhesive"

High quality flame retardant emf shielding fabric for radiofrequency and microwave shielding. Rugged rip-stop polyester substrate (for superior strength and handling), Nickel and Copper plated (for excellent shielding and low corrosion), then coated on one side with a non-conductive hot melt adhesive (activates at 130°C = 266°F) so you can iron it on to cotton, wood, glass or paper, or roll it into a tube and heat seal the seam! You can turn almost any surface or fabric into a high performance RF shielding material. Maximum temperature is 200°C (=392°F). Can also be cut and sewn like ordinary fabric.

This fabric offers an amazing shielding performance: 70 dB over 30 MHz to 3 GHz, and 55-65 dB over 24-40 GHz. Will also block virtually all ELF & VLF electric fields when grounded. Great for shielding extension cords and computer cables. Connect strips of it to make a sheet shield under your bed or hang it on the wall. Makes a great liner for drapes too! Line a vest or a hat to protect your vital organs from radiowaves and electric fields. It doesn't breathe well, and Nickel may cause skin irritation, so plan to line it with cotton if you will be using it against the skin. 230 g/m², 0.17 mm thick. UL 94V-0 level flame retardant. RoHS Compliant. Gray, 13 inch wide.

Thickness: 0.17 mm

Linear Foot Image

How much is a linear foot"

Because we offer so many different fabrics, of different widths, the easiest way to order is by specifying how long the piece of fabric will be. We describe the length of the fabric purchased in linear feet. So, for example, if you order 22 linear feet of a material, you will get a piece that is 22 feet long x the width of the material. The width of each material is listed near the end of the product description.
