From the look and soft feel of NaturaShield, you would never know it was a high performance shielding fabric. Advance technology has created a fiber which has the conductive components on the inside, with pure natural cotton on the outside.
The result is a fabric which is gentle to the skin, has a great feel, and still provides 20-35 dB from 100 MHz to 2.2 GHz, and residual performance up to 10 GHz, according to independent test results.
Surface resistivity is 109 Ohm/sq. Perfect for bedding, clothing, drapes and most other applications where you want shielding without the harshness of metallized fabrics. Completely machine washable and dryable (cool) without losing shielding performance, cuts and sews like ordinary cotton, 125 g/m², 60" wide, white as snow with a fine grey grid.

NEW IMPROVED
MICROWAVE ABSORBING SHEET
Now with plastic coating for easier handling
Carbon is conductive in some forms, and a very good microwave absorber. Using non-woven nearly-pure carbon fibers, to achieve both good microwave shielding and high absorption, this unique material has the following specifications:
Carbon base material (without plastic laminate):
- Width: 48 inch (1219 mm)
- Weight: 34 g/m²
- Thickness: 18 mil (0.445 mm)
- Resistivity: ~3 Ohms per square
- Tensile: 47 N/15mm
We are pleased to offer this improved version of our very low cost microwave absorber sheet. This version is plastic laminated on both sides. This gives better durability and easier handling. Dust is reduced and skin contact is not a problem.
Application Note:
To create a super high peformance enclosure, you can combine a layer of this Microwave Absorber material with a layer of a high performance fabric shield such as Flectron or Zelt. Line the inside of the shield with Absorber... it will scavenge any RF which might leak in.
Super light weight. Can be used to line walls and containers, make drapes or partitions. Does not permit air circulation, minimal light penetration.
Still 48 inches wide, but surface is non-conductive due to laminate. Request roll shipping if you need to avoid creases from folding.

Shielding Magnetic Fields? |
|
As far as we know, no fabric currently exists which can offer magnetic field shielding (and we keep looking!). However, with very little effort, you can make the next best thing using a little spray adhesive to create a 3-layer sandwich with MetGlas foil on the inside and the fabric of your choice on the two outer sides. The resulting "fabric" has a slight stiffness and is a bit crinkly so you wouldn't want to use it for underwear, but it has great shielding properties and makes great vests, aprons, hats, sheets and more. Just follow these simple steps: 1] Spread old newspaper or a large dropcloth on a flat surface. 2] Lay the first fabric layer out flat. Here's what it would look like:  3] Spray the entire top side of the fabric with a spray adhesive (easily found at most fabric/craft stores). 4] Lay strips of MetGlas onto the fabric until the entire fabric is covered. Make sure to achieve a slight amount of overlap at all seams but avoid bunching and wrinkles. Handle the foil carefully… it has sharp edges! Here's what it would look like:   |
