| OHMS/SQ. | MATERIAL | DESCRIPTION |
| >1013 | Insulative | Insulators and base polymers. These materials are not protective against static electricity. |
| 1010 to 1012 | Anti-Static | Initial charges are suppressed, but may only be surface resistant. |
| 106 to 109 | Dissipative | No or low initial charge. Prevents discharge to or from human contact. |
| 103 to 105 | Conductive | No initial charge, but still provides an easy path for bleed off to another object. |
| 1 to 103 | Shielding Composites | Employs nickel coated carbon fibers to omit EMI only in specific products. |
| 10-3 to 1 | Carbons | Carbon powder and fiber. |
| < 10-3 | Metals | Stainless steel, bronze, and copper. |
