Description
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 PerformanceWe 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.
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.

LAMINATED MICROWAVE ABSORBING SHEET
RF Shielding with Minimal Reflection
Carbon is conductive in some forms, and a very good microwave absorber. We
are pleased to offer this improved version of our very low cost microwave
absorber sheet.
Now with plastic coating for easier handling and better durability. Non-woven
nearly pure carbon fibers, achieve both high microwave shielding & high
absorption. Eliminates annoying reflection. Very unique!
Width: 48 inch
Weight: 34 g/m²
Thickness: 26 mil (0.64 mm)
Carbon Resistivity: ~3 Ohms/sq
(but surface is not conductive due to laminate)
Super light weight. Can be used to line walls and containers,
make drapes or partitions. One special application of this material uses a layer of
high performance reflective fabric, such as Pure Copper Taffeta, CobalTex, or
Ni/Cu RipStop plus a layer of RF Absorber (on the side where the “quiet zone” is)
to achieve super performance, minimal leakage, and low reflections.
Application Notes:
1- Double or triple the layers of MW Absorbing Sheet to increase effectiveness.
2- To create a super high performance enclosure, you can combine a layer of this
MW Absorber material with a layer of a high performance fabric shield. 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
Washing Instructions: Do not machine wash or dry clean. Dry brush or wipe
with damp cloth. Do not iron.
This material is not intended for garments nor bedding. Black. Request roll
shipping if you need to avoid creases from folding.
