Copper Wire Mesh


When Only Pure Copper Will Do

Highly transparent and conductive. Woven pure copper, fine wire mesh is useful for RF and electric field shielding, Faraday cages and grounding. Great for building your own RF shielded Faraday enclosure to test your electronics with no Radio Frequency interference to skew your test results. Mesh is flexible and cuts easily with scissors. Will conform to most shapes or lay flat easily. Can be soldered. Easy to connect a ground cord.

Also very decorative, but susceptible to tarnish. It will turn brown, then green, when exposed to the environment, so definitely not for exterior use.

- 16 wires per inch
- 0.011 inch (0.27mm) Wire Diameter
- 0.051 inch (1.32mm) openings
- 68% open
- 2.3 oz/ft² (0.65 kg/m²)

Skin-Blok Skin-Blok


Attractive Peel-and-Stick RF Shielding

Want shielding that is more decorative? Want to block light? Want easy to install? Skin-Blok shielding contact film is the answer. Good shielding for wireless radio frequency (wifi), shield cellphone cases and smart meter shielding. Light-weight and waterproof, it wipes clean with a damp sponge.

Skin-Blok "Orange peel" type texture hides irregularities in the wall and makes seams almost disappear. Can be left exposed for a high-tech look, or cover over it with wall paper, curtains or a wall hanging. Can also be attached to the back of a headboard, mirror or picture. Place it on a door, window, or any other fairly rigid surface. Could even be used as a backsplash. You can even line small enclosures for your wireless routers, cellphones, medications or homeopathic remedies, etc.

Simply trim to size with scissors, clean the surface well, and peel and stick it in place like contact paper. Mild adhesive, allows repositioning or removal if you change your décor. Surface is poorly conductive. 20-25 dB attenuation. For indoor use only.
You get a roll that is 24 inch wide x 16 feet long, 2 color options: silver or gold.

Now with plastic coating for easier handling

MW Absorbing Sheet 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 RF 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

MW Absorbing Sheet Performance We are pleased to offer this improved version of our very low cost microwave absorber sheet. This version is plastic (polypropylene) laminated on both sides. This gives better durability and easier handling. Dust is reduced and skin contact is not a problem. New testing shows 26-36 dB attenuation over 1-10 GHz, and 60-70 dB over 24-40 GHz.

Application Notes:
1- Double or triple the layers of MW Absorbing Sheet to increase effectiveness.
2- To create a super high RF performance enclosure, you can combine a layer of this Microwave Absorber material with a layer of a high performance fabric shield such as Pure Copper Polyester or Nickel Copper Ripstop to provide the highest RF shielding. Line the inside of the shield with Absorber... it will scavenge any RF which might leak in.
3- Grounding is not necessary with this material.
4- Minimize repeated bending/flexing of this material

Super light weight. Can be used to line walls and containers, make drapes or partitions. Does not permit air circulation, minimal light penetration.

48 inch wide, but surface is non-conductive due to laminate. Request roll shipping if you need to avoid creases from folding.

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.
